Answer:
Explanation: The ray of light strikes the mirror at an angle of 20 degree,it means it will make an angle of 70 degree (90-20) with the normal. and also from the laws of reflection from mirror,we know that the angle of reflection is always equal to the angle of incidence.

Answer:
Explanation:
a)
Angle of incidence = 90-20 = 70 degrees.
Angle of reflection = Angle of incidence = 70 degrees.
b)
For normal incidence, angle of incidence = Angle of reflection = 0 degrees.
I hope this answer will help you
