S : Source of Light (Lamp)[br]DE : Reflecting surface (Plane Mirror)
What Is Reflection of Light?[br]
When a light ray approaches a smooth polished surface (such as plane mirror) and bounces back at the same angle as the angle of incidence. The angles of incidence and reflection are measured from a normal to the plane of the plane mirror.
What is the nature of the image formed by the plane mirror?[br]
A plane mirror always forms a virtual and erect image of the object.
State the laws of reflection.
[list][*]The angle of incidence is equal to the angle of reflection.[/*][*]The incident ray reflected ray and the normal at the point of incidence all lie in the same plane.[/*][/list]
If the reflecting surface is very smooth, the reflection of light that occurs is called specular or regular reflection. The laws of reflection are as follows:[br][list=1][br][*]The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.[br][/*][*]The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.[br][/*][*]The reflected ray and the incident ray are on the opposite sides of the normal.[/*][/list]
