Questions
The light ray is incidence at angle of 60° on a prism of angle 45°. When the light ray fails on the other surface at 90°, the refractive index of the material of prism and the angle of deviation δ are given by
detailed solution
Correct option is D
From figure it is clear that ∠e=∠r2=0From A=r1+r2⇒r2=A=45o∴μ=sin isin r1=sin60osin45o=32Also from i+e=A+δ⇒60+0=45+⇒δ=15oTalk to our academic expert!
