Question

EXAMPLE When two mirrors are inclined at an angle of 60° with each other, find the glancing angles and angle of deviations at both the mirrors if the angle of incidence of a light ray is 45º Draw its ray diagram​

Answer 1

Answer:

=

45°

15°

i2 12

-

Glancing angle at

M₁901 = 90 - 45°

45°

=

Glancing angle at

M₂ 90 12 = 90 - 15

= 75°

Angle of deviation at

M₁ = 180 - 2i1

= 90°

Angle of deviation at

M₂ 180 2i2 =

=

=

150°
