Question

define the terms reflection . state two laws of reflection if incident angle is 45 degree then what will be the angle of reflection ?

Answer 1

Answer:

First, we consider reflection, as shown in the diagram below for a light wave striking a surface. We identify the incoming ray as the incident ray and the outgoing ray as the reflected ray. Concomitantly, the angleθ

i

that the incoming ray makes with a line (dashed in the diagram) normal to the surface is called the angle of incidence. The angle θ

r

for the reflected ray is called the angle of reflect.

The law of reflection states that the angle of incidence is equal to the angle of reflection, or, stated mathematically.

And also the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.
