(a) Draw a diagram to show the reflection of light from a plane mirror.Label the following on the diagram:
(a) Plane mirror (b) Incident ray (c) Reflected ray
(d) Point of incidence (e) Normal (f) Angle of incidence
(g) Angle of reflection
(b) State the laws of reflection of light.
Suppose you have a plane mirror that reflects light. When light strikes the mirror, the light is reflected off the surface. The law of reflection says that:
Statement 1: The angle of incidence (incoming ray) is equal to the angle of reflection (outgoing ray).
Statement 2: The angle is measured from a perpendicular line to the surface called as Normal.
Statement 3: Incident ray, reflected ray and the normal does not lie in the same plane.
Statement 4: The law works for the plane as well as for curved surfaces.
