Question

if the light ray falls on the plane mirror suffers an angle of deviation 150 after one reflection then find the angle of incidence and glance ane of reflection ​

Answer 1

Answer:

Since angle of incident =angle of reflection

Hence r=30

0

And here angle of deviation,

δ=180

0

−(i+r)

δ=120

0

Answer 2

Answer:

Since angle of incident =angle of reflection

Hence r=30°

And here angle of deviation,

δ=180° −(i+r)

δ=120°
