Questions
The angle of incidence for a ray of light at a refracting surface of a prism is . The angle of prism is . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are
detailed solution
Correct option is D
Given, i=45°,A=60° Since the ray undergoes minimum deviation, therefore, angle of emergence from second face, e=i=45°∴δm=i+e-A=45°+45°-60°=30°μ=sin(A+δm2)sin(A2)=2Talk to our academic expert!
