This phenomenon is called refraction illusion. A Refraction Illusion occurs when light bends as it passes through different mediums, such as water, glass, or air layers of varying densities.

The Moon’s size on the horizon has puzzled humans for millennia. Despite ancient philosophers and modern scientists tackling the question, there's still no consensus. Theories range from optical ...

A ray diagram showing refraction at the boundary between air and glass Refraction can cause optical illusions as the light waves appear to come from a different position to their actual source.

The direction of the ray may also change. This property of waves is called refraction and commonly occurs with light rays. A normal is a dotted line drawn perpendicular to the surface of the ...
