REFLECTION OF LIGHT
Reflection is one of the unique properties of light. It is the reflection of light, which enables us to see any object.
Reflection: The bouncing back of rays of light from a polished and shiny surface is called reflection or reflection of light. It is similar to bouncing back of a football after colliding with a wall or any hard surface.
Laws of reflection:-
(i) The angle of incidence is equal to the angle of reflection, and
(ii) The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane.
The angle of incidence is denoted by 'i' and angle of reflection is denoted by 'r'. The law of reflection is applicable to all types of reflecting surface.
Mirror is a shiny polished object (glass) which reflects most of the rays of light falling upon it. One side of mirror is polished with suitable material to make the other side reflective.
Real Image: Image which is formed in front of the mirror and it can be obtained on a screen is called real image.
Virtual Image: Image which is formed behind the mirror and cannot be obtained on a screen is called virtual image.
