Before discussing the properties of a concave mirror we have to understand some point about the image formed by a concave mirror. Characteristics of Plane Mirrors: 1. Image : It is a point where atleast two light rays actually meet or appear to meet. The first mirrors used by humans were most likely pools of water. Its value is 3 × 10 8 ms -1. Plane mirrors 1. CLASS 12 NEET (UG) 2021. 8788563422. (2) The incident ray, the reflected ray and the normal at the point of incidence, all lie in the same plane. Image Formation by a Plane Mirror. This process is called reflection of light. 3. Secondly, the mirror reflects the ray of light from the centre on the same path. The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror. CLASS 10 FOUNDATION. A plane mirror which is a highly polished surface reflects the light on it.This is the regular reflection.However,irregular surfaces also do the same and it is called irregular reflection.I am not able to understand that if both are reflecting surafces why does a plane mirror form an image but a rough surface doesa not. Properties of images formed by a plane mirrors:1. 4. Another important aspect covered in class 10 light chapter is the type of mirrors. We see our image in the mirror when we stand in front of it. There are 2 kinds of mirrors: Plane Mirror– A reflecting surface that is a plane. → When light falls on a surface, following may happen: (i) Reflection. Plane mirrors in physics are the ones that have a flat reflecting surface and produce always a virtual image. An incident ray of light AP from point A of the object AB falls on the mirror MM’ at point P. Solved Example for You Q. (i) Angle of incidence is equal to the angle of reflection. The mirror is fixed. Laws of Reflection. Students must learn how to draw the ray diagrams in contrast with the mirror and the type of ray. a) Laws of reflection of light :- i) The angle of incidence is equal to the angle of reflection. These were some applications of plane mirrors. (ii) Refraction. 0 votes Properties of a Concave Mirror. A smooth and highly polished reflecting surface are is a mirror. 2.

Class 10. → Bouncing back of light when it strikes on a polished surface like mirror. A ray of light strikes a reflective plane surface at an angle of 42 o … 1 ) When the object is moved towards the concave mirror, the size of the image increases and vise versa. A point object is moving with 3 i ^ + 4 j ^ in front of the plane mirror. A plane mirror is a flat, smooth reflective surface. A ray optics plane mirror is a mirror consisting of a flat reflective surface. CLASS 12 JEE (Main & Advanced) 2021. For any content/service related issues please contact on this number . Image is laterally inverted i.e., image is inverted sideways with respect to the object. I.e. Images formed by a plane mirror are “Always Virtual”. These are mirrors that are flat. (ii) It forms a virtual image. Images formed by a plane mirror are “Erect/Upright”. In this section we deal with plane mirrors. This reflection obeys the law of reflection and is the type that happens with a flat mirror. Life Processes - 1 6 Lecture 5.1. a. (i) Plane mirror forms an erect image. Reflection. Properties of the image in a plane mirror. The image formed by a plane mirror is virtual and erect.2. Concept of mirrors-plane mirror, concave mirror and convex mirror and related terms. PRMO NTSE Class 11. A plane mirror always forms a virtual image that is upright, and of the same shape and size as the object, it is reflecting. A plane mirror has various exclusive features and characteristics corresponding to the image that it forms, which are as follows: A plane mirror always forms a virtual image. Locating an Image in a Plane Mirror. Explore reflection and refraction of light, concave & convex mirrors, etc. CLASS 12 FOUNDATION (JEE) 2021. The plane mirror is the mirror with a planer and flat reflective surface, It makes the image of the objects in front of it, The images appear behind the plane at which the mirror lies, The straight line drawn from the part of an object to the part of its image makes a right angle with, and it is bisected by the surface of the plane mirror. Applying this to triangles PAB and QAB in and using basic geometry shows that they are congruent triangles. Images formed by plane mirrors are virtual, upright, left right reversed, the same distance from the mirror as the object's distance, and the same size as the object. iv) The images are laterally inverted. The image is formed as far behind the mirror as the object is in front of it i.e., object distance is equal to the image distance. CBSE Class 10 Science Chapter 10 Light – Reflection and Refraction Notes Properties Of Light An electromagnetic wave so does not require any medium to travel Light tends to travel in a straight line Light has dual nature i.e., wave as well as particle Light casts shadow Speed of light is maximum in vacuum. If the answer is not available please wait for a while and a … 3. Characteristics of the image formed by a plane mirror : It is virtual; It is erect and of the same size as the object; The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror. One of the important characteristics of the image is that it is laterally inverted. Question 3: Name the mirror that can give an erect and enlarged image of an object. The incident ray, the reflected ray and the normal ray lie in the same plane. Life Processes of living Beings, Nutrition, Mode of Nutrition and … Reflection of Light | 10th Class | Lecture -02 | Plane Mirror | Properties Of Image Spherical Mirror– A reflecting surface that is part of a hollow sphere. Plane mirror- Definition, Properties and Ray Diagram. The mirror formula is 1/f = 1/v + 1/u and it is also applicable to a plane mirror. (iv) Image is formed at the same distance behind the mirror as the object stands in front of it. Even these mirrors are used in shops to keep an eye on the customers. Images formed by the plane mirrors are always virtual in nature. CLASS 9 FOUNDATION. A spherical mirror is a mirror that has a consistent curve and a constant radius of curvature. Please Register or login to watch this video. Uses of plane mirrors for security and safety. → Magnification of Spherical mirrors Introduction → Light is the form of energy that provides sensation of vision. → Some common phenomena associated with lights are image formation by mirrors, the twinkling of stars, the beautiful colours of a rainbow, bending of light by a medium and so on. Properties of Light Some of its properties are: A real image is capable of being seen on the screen. The earliest known manufactured mirrors were polished stone pieces. Yes, definitely! The size of the image is equal to the size of the object. Question 4: Why do we prefer a convex mirror as a rear-view mirror in vehicles? It means if you raise your left hand it would appear in the plane mirror that you have raised your right hand. Question 4. Firstly, for a spherical mirror-like CM the focal distance is half of the radius of the focal length. Free Powerpoint Templates 3. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. b. Its size is equal to that of the object. c. Images formed by a plane mirror are of “same shape and size” as that of an object. NCERT Solutions For Class 10. Answer: When an object is placed between the pole and the principal focus of a concave mirror, the image formed is virtual, erect, and enlarged. (iii) Size of the image is same as that of the object. One of the important characteristics of the image is that it is laterally inverted. Types of mirror (a) Plane mirror: When the polished surface is plane and the reflection is regular then it is called as a plane mirror. A plane mirror is placed along the x-axis facing negative y-axis. You are very important to us. Now, we know that for a plane mirror v = -u Therefore 1/f = -1/u +1/u = 0. ... PROPERTIES OF PLANE MIRROR Video is paused. Image Formed by Plane Mirror: Characteristics of Image: (i) Virtual … A plane mirror is a mirror with a planar reflective surface. The image is obtained by using a converging lens or a concave mirror. ii) The incident ray, the reflected ray and the normal to the mirror at the point of incidence all lie in the same plane. (iii) Absorption. Reflection of light :- In this case light ray reflects back into the same medium after reflection by reflecting surface. In Text Questions FA 3 & SA 2 SYLLABUS : FA Syllabus: Basic concept of light and its properties Reflection of light and laws of reflection of light. But have you ever thought about its properties? For the ray starting from point A and travelling in a horizontal direction towards point E, the angle of incidence is 0 and hence it retraces its path. Similarly, the ray starting from A and travelling towards point C follows the law of reflection. Image formed is of the same size as the object.3. Images formed by the plane mirrors are erect/ upright and is of the same size as of the object. The images formed by a spherical mirror can either be real or virtual. are solved by group of students and teacher of Class 10, which is also the largest student community of Class 10. > Mirrors: A smooth, silver surface which reflects light regularly is called a mirror. Mirrors are also used in blind turns of busy roads to see the vehicles coming from other side. Characteristics of the images formed by plane mirrors are: i) The image formed is of the same size as that of the object. It is formed at the same distance behind the mirror as the object is in front of the mirror. 2. The law of reflection tells us that the angle of incidence is the same as the angle of reflection. ii) The image is same size as the object. When light rays strike the plane mirror, the angle of reflection is equal to the angle of incidence. It is always virtual and erect. Plane Mirror. Let us suppose an object AB of size ‘h’ on the left-hand side of the mirror at a distance ‘u’. Q4) State the characteristics of the image formed by a plane mirror. Keep Playing Keep Paused PROPERTIES OF PLANE MIRROR. The word ‘AMBULANCE’ is opposite because when the driver of the vehicle ahead of the ambulance looks in her/his mirror, the person can read it as ‘AMBULANCE’ and give way to it. Let us take a mirror MM’ as shown in the diagram given above. 4. 2 ) When the object is moved towards the concave mirror, the image distance from the mirror also increases except one situation in which the object is placed between the focus and pole of the mirror. Mirrors are used while looking for explosives underneath a vehicle. For any given surface of a plane mirror, these above terms should add up to form 1. Thus f is at infinity. The Questions and Answers of Explain the reflection by a plane mirror ? This means that the distance PB from the object to the mirror is the same as the distance BQ from the mirror to the image. Solution: An image formed by a plane mirror has the following characteristics: Virtual and erect. Laterally inverted image (image of … iii. Spherical Mirrors 5 i) The image is erect. Free Powerpoint Templates PRODUCERS : SEHAJPAL SINGH & MANJOT SINGH BUDHA DAL PUBLIC SCHOOL, Patiala,India Class Xth (2010-11) 2. Mon to Sat - 10 AM to 7 PM The size of the image depends upon the placement of the object. It is laterally inverted. Properties of image formed by a plane mirror: 1. iii) The virtual and erect image is formed. answered Mar 10, 2016 by prashanth Basic (54 points) In conclusion, plane mirrors produce images with a number of distinguishable characteristics. Group Discussion iv. Most commonly used are plane mirrors. ii) Images are formed behind the mirrors and are at the same distance from the mirror as that of the object. Mirrors are defined as one side-polished surface that can reflect the light rays. According to their reflection of light, they can be classified into 3 types as concave, convex and plane mirror. NCERT Solutions for Class 10 Social Science; ... To obtain a real image the light source and the screen must be placed on the same plane. A virtual image is produced when the light rays from a source don’t cross or meet at a point to form an image. other than the uses discussed in the class.
