MCQ
'Mirage' is a phenomenon due to
- AReflection of light
- BRefraction of light
- ✓Total internal reflection of light
- DDiffraction of light
✓
Answer
Correct option: C.
Total internal reflection of light
c
(c) Mirage is a phenomenon observed due to the total internal reflection of light when light travels from a denser medium to a rarer medium. When the angle of incidence of light is more than the critical angle for the two adjacent media, the light gets totally internally reflected.
