Which of the following is optical illusion? (1) Rainbow (2) Earthshine (3) Halo (4) Mirage
by

1 Answer

Answer :

(4) Mirage Explanation: A mirage is a naturally occurring optical illusion or phenomenon in which light rays are bent due to refraction in layers of air of varying density. The image usually is upside down, enhancing the illusion that the sky image seen in the distance is really a water or oil puddle acting as a mirror.
