For a light ray to undergo total internal reflection ( i = angle of incidence, i _ c = critical angle )

Options

  1. Alight travels from denser to rarer medium and i i _ c .
  2. Blight travels from rarer to denser medium and i i _ c .
  3. Clight travels from denser to rarer medium and i i _ c .
  4. Dlight travels from rarer to denser medium and i i _ c .

Correct answer

C. light travels from denser to rarer medium and i i _ c .

Step-by-step solution

So in order for total internal reflection to take place; The rays of light must travel from a dense medium to a less dense medium. The angle of incidence must be greater than the critical angle.
