In an equilateral prism the ray undergoes minimum deviation when it is incident at an angle of 50^ . The angle of minimum deviation is

Options

  1. A50^
  2. B40^
  3. C25^
  4. D20^

Correct answer

B. 40^

Step-by-step solution

When a ray undergoes minimum deviation, i= A+ _m 2 For an equilateral triangle, aligned & A=60^ & 50= 60+ _m 2 & _m=40^ aligned
