Critical angle of light passing from glass to air is minimum for wavelength of

Options

  1. Ared colour
  2. Byellow colour
  3. Cgreen colour
  4. Dblue colour

Correct answer

D. blue colour

Step-by-step solution

i _ c = 1 n therefore i _ c will be minimum when n is maximum which in this case is for blue light.
