There refraction and total internal reflection takes place. The ground will be hot and the air will be cool comparatively. Hence the layer just above the ground would also be hot. when the light enters from cool air to hot air, the refraction takes place and then total internal reflection happens. As a result it looks like a bend one like mirage.

Understanding Mirage Formation
A mirage is an optical phenomenon that occurs due to specific interactions of light with varying temperatures in the atmosphere. The correct answer to the question about which phenomena contribute to mirage formation is option 'C' (Reflection of light and Refraction of light).
Key Phenomena Involved
- Reflection of Light
- Light can reflect off surfaces, and in the case of a mirage, this can involve the light bouncing off the ground and into the viewer's eyes.
- Refraction of Light
- Refraction occurs when light passes through layers of air at different temperatures. Hot air is less dense than cooler air, causing light rays to bend. This bending creates the illusion of water or a reflective surface, resulting in the appearance of a mirage.
Why Other Phenomena Do Not Apply
- Terrestrial Heating
- While terrestrial heating contributes to temperature differences in the ground and air, it is not a direct optical phenomenon. It creates the conditions necessary for refraction but does not directly cause the mirage itself.
- Diffraction of Light
- Diffraction is the bending of light waves around obstacles and openings. This phenomenon does not play a significant role in the formation of a mirage.
Conclusion
In summary, a mirage is primarily formed through the refraction and reflection of light, especially as it interacts with layers of air at varying temperatures. This combination creates the visual effect that mimics water or a reflective surface on roads or deserts. Understanding these principles is crucial for grasping the underlying science of mirages.
