Questions
A glass prism has refractive index , and refracting angle 30°. One of the refracting surface of the prism is silvered. A beam of monochromatic light will retrace it path if its angle of incidence on the unsilvered refracting surface of the prism is
detailed solution
Correct option is C
A =r1+r2 30°=r1+0 or r1=30° Now, sin isin 30°=2 or sin = 2×12 or i = 45°Talk to our academic expert!
