Question

Consider the following natural phenomena:
1. Terrestrial heating
2. Reflection of light
3. Refraction of light
4. Diffraction of light
Due to which of these phenomena is mirage formed?

• A. 1 and 2
• B. 2, 3 and 4
• C. 2 and 3
• D. Only 4

Hint:

When studying optical phenomena like mirages, focus on the refraction of light and its behavior with temperature gradients.

Answer 1

The Correct Option is C

A mirage is formed due to the refraction and sometimes reflection of light. When light passes through layers of air at different temperatures (caused by terrestrial heating), the light bends, creating the illusion of water or distant objects. Diffraction does not play a significant role in the formation of a mirage.
