Detailed explanation-1: -Answer: Option A Solution: Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent).
Detailed explanation-2: -Hence, the Mirage is caused due to atmospheric refraction and the total internal reflection.
Detailed explanation-3: -Fata Morgana mirages also show alternating compressed and stretched zones. The optical phenomenon occurs because rays of light bend when they pass through air layers of different temperatures in a steep thermal inversion where an atmospheric duct has formed.
Detailed explanation-4: -Mirages are produced by atmospheric refraction and are mainly seen in settings where there are large variations in the air temperature, such as in deserts or over cold bodies of water.
