A ray of light passes through an equilateral prism such that the angle of incidence (i) is equal to angle of emergence (e). The angle of emergence is equal to ( 3 4 )^ th the angle of prism. The angle of deviation is

Options

  1. A20^
  2. B30^
  3. C39^
  4. D45^

Correct answer

B. 30^

Step-by-step solution

i = e =60^ 3 4 =45^ ( prism is equilateral ) Angle of Deviation: = i + e - A =45^ +45^ -60^ =30^
