Questions
A ray of light falls at angle of incidence 60° on one face of prism of angle 30°. Emerging ray makes an angle of 30° with incident ray. The refractive index of material of prism is
detailed solution
Correct option is D
given i1=600, A =300, D =300 D=i1+i2-A solving for i2 and i2 =0 then r2 =0 and r1=A=300 μ=sini1sinr1 =sin600sin300=3Talk to our academic expert!
