Which set of colours will come out in air for a situation shown in figure?

Options

  1. AOrange, Red and Violet
  2. BBlue, Green and Yellow
  3. CYellow, Orange and Red
  4. DAll

Correct answer

C. Yellow, Orange and Red

Step-by-step solution

We know, i_C= 1 Also 1 Thus i_c Therefore, for higher value of critical angle will be more Hence Yellow, Orange and Red will come out to air.
