Question

a) State the two laws of reflection of light.

b) What is the angle of incidence when a ray of light is incident normally (perpendicularly)

on a plane mirror?

c) An incident ray makes an angle of 75° with the surface of the plane mirror. What will be

the angle of reflection?

d) The angle between the incident ray and reflected ray is 100°. What is the value of angle

of incidence?​

Answer 1

Answer:

The angle of incidence when a ray of light is incident normally on a plane mirror is zero degrees because the ray is incident normally

I hope it is useful for you and have a sweet day today and please follow me guys and thanks to my answer please

Answer 2

Answer:

a)

Explanation:

The incident ray the reflected ray and the normal lie in the same plane at the point of incidence is always equal to the angle of reflection .

hope it will help you
