Question

kya hai jo dikhai deta hai par hota nahi

Answer 1

Mirage effect. It can be observed on roads, deserts, etc during summer. This is due to the phenomenon known as refraction. As the hot surface warms the air immediately above it to a higher temperature than the air higher up. A light ray grazing the surface under those circumstances is bent, or refracted, upward. That's because light travels faster in warmer, less dense, air than in denser cold air. The faster motion of the lower part of a light ray speeds ahead of the upper part, causing it to bend (refract) upward. TOH YEH HOTA BHI NAHI HAI AUR DIKHTA BHI HAI.
