1.

Haveyou seen that objects beyond and above a holi fire appear to be shaking?

Answer»

Solution :1. Local atmospheric conditions affect the refraction on light.
2. The air NEAR holi flames is hot and hence rarer than the air aboveit.
3 The refractive indexof air keep increasing and the direction of light rays coming from objects BEYOND the holi fire changes DUE to changing refractive index above the fire.
4. Thus, the objects appear to be MOVING.
