An optical illusion which occurs mainly in deserts during hot summers is based on the principle of-

Reflection

Interference

Dispersion

Total internal reflection

Total internal reflection is defined as:

The phenomenon which occurs when the light rays travel from a more optically denser medium to a less optically denser medium.

Following are the two conditions of total internal reflection:

1.The light ray moves from a more dense medium to less dense medium.
2,The angle of incidence must be greater than the critical angle.
