Class 10 Physics Light Reflection Refraction
Introduction
Introduction
An object reflects light that falls on it. This reflected light, when received by our eyes, enables us to see things.
We are able to see through a transparent medium as light is transmitted through it.
The laws of reflection are:
The angle of incidence is equal to the angle of reflection
The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane.
These laws are applicable to every surface.
Properties of image formed by a plane mirror:
Image formed by a plane mirror is always virtual and erect.
The size of the image is equal to that of the object.
The image formed is as far behind the mirror as the object is in front of it.
The image is laterally inverted.
