Question

The angle etween the incident ray and the reflected ray is 80°. Then the angle of incidence is:​

Answer 1

Answer:

The angle between the reflected ray and the normal is known as the angle of reflection. ... The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Answer 2

40°

Explanation:

Let angle i = angle r = x

ATQ,

x + x = 80°

2x° = 80°

$x = (\frac{80}{2} )$

x° = 40°
