Interference
B.

C.
Polarisation
D.
Total internal reflection
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Mirage is a phenomenon due to total internal reflection of light. It happens when the light goes from optically denser medium (cool air) to rarer medium (hot air) and angle of incidence is equal to or greater than the critical angle resulting total internal reflection at the interface of the two mediums.
