Q516

In total internal reflection, the light travel from

A.
Rarer to denser medium and it occurs with no loss of intensity
B.
Denser to rarer medium and it occurs with no loss of intensity
Answer
C.
Rarer to denser medium and it occurs with loss of intensity
D.
Denser to rarer medium and it occurs with loss of intensity

Answer: Option B

Solution

Answer: Option B
Solution:
For total internal reflection to occur the light must travel from a dense medium to a less dense medium (e.g. glass to air or water to air). As the angle of incidence increases so does the angle of refraction.
