Question

Quizplus · Accepted Answer

Mirages occur due to the refraction of light, which happens when light travels from a denser to a less dense medium, causing the light to bend. Near the ground, especially on hot days, the air is less dense compared to the cooler, denser air higher up. This difference in density causes light to bend or refract, creating the illusion of a mirage. Therefore, both statements A and B are correct, as they describe the conditions under which the density of air changes, affecting the speed of light and resulting in a mirage.
