The phenomenon which causes mirage is – (1) Interference (2) Diffraction (3) Polarisation (4) Total internal reflection
by

1 Answer

Answer :

(4) Total internal reflection Explanation: Mirage is caused by total internal reflection in deserts where due to heating of the earth, refractive index of air near the surface of earth becomes lesser than above it. A ray of light coming from a distant object gets refracted from a denser to a rarer medium.
