A ray of light travelling in a transparent medium of refractive index falls, on a surface separating the medium from air at an angle of incidence of 45^ . For which of the following value of the ray can undergo total internal reflection?

Options

  1. A=1.33
  2. B=1.40
  3. C=1.50
  4. D=1.25

Correct answer

C. =1.50

Step-by-step solution

For total internal reflection aligned & i > c & i > c & 45^ > 1 & > 2 & >1.4 aligned
