For a light ray to undergo total internal reflection ( i = angle of incidence, ic = critical angle) (a) light travels from denser to rarer medium and i ic. (d) light travels from rarer to denser medium and i > ic.

Answer: (c). TIR conditions: light must go from denser to rarer medium. The angle of incidence must exceed the critical angle, i > ic. So the answer is (c).

Total Internal Reflection

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

Show answer and solution

Answer: (c)

TIR conditions: light must go from denser to rarer medium.
The angle of incidence must exceed the critical angle, $i > i_c$ .
So the answer is (c).
