Question

Quizplus · Accepted Answer

Mirages are caused by variations in air density, which causes light to be refracted and can create the illusion of objects appearing in different locations or in different shapes than they actually are. This is why mirages are commonly seen on hot, sunny days when there is a large temperature difference between the ground and the air above it. Reflection, diffraction, and scattering of sunlight may all contribute to the overall effect, but they are not the underlying cause of mirages.
