Answer 1

Explanation:

HENCE according to law of reflection angle of incidence is equal to angle of reflection hence the angle made by incidence from noraml is 80 degree so angle of incidence is 80 and also the reflection angle is 80 thankyou

Answer 2

Answer:

a) Angle of incidence = 90° - 10° = 80°

and according to second law of reflection

angle of incidence = angle of reflection

b) Angle of reflection = 80°

c) refer to the attachment

Hope you got your answer

Have a great day ahead
