Question

How do u solve the angle of prisim
Angle of incidence, angle of emerge, angle of refraction

Answer 1

Answer:

Since the refraction angle (r 2) of the emergent ray will be equal to the critical angleθ c .

The critical angle is given as, sinθ c

= μ1 sinθ c

= 1.51 θ c

=41.81 ∘

The refracted angle is given as, r 1

=60−41.81 r 1

=18.19

The incidence angle is given as, sinr 1 sini

=μ

sin18.19 ∘ssin

=1.5

i=27.92 ∘

Thus, the angle of incidence is 27.92 ∘ .
