For a light ray to undergo total internal reflection, light must travel from ( i = angle of incidence, i_C= critical angle )

Options

  1. Ararer to denser medium and i
  2. Bdenser to rarer medium and i
  3. Cdenser to rarer medium and i>i_c
  4. Drarer to denser medium and i>i_c

Correct answer

C. denser to rarer medium and i>i_c

Step-by-step solution

Condition of total internal reflection: The conditions to be satisfied for total internal reflection are as follows - 1) Light must travel from a denser to a rarer medium. 2) The angle of incidence i must be greater than the critical angle i_C the two media.
