Questions
A ray of light is incident normally on one of the face of a prism of angle 30° and refractive index . The angle of deviation will be
detailed solution
Correct option is D
A=30o,μ=2. As we knowA=r1+r2=0+r2⇒A=r2Applying Snell's law for the surface AC1μ=sin r2sin e=sin Asin e⇒12=sin30osin e⇒e=45oδ=e−r2=45o−30o=15oTalk to our academic expert!
