Atmospheric refraction near the ground produces mirages. Such refraction can also raise or lower, or stretch or shorten, the images of distant objects without involving mirages. Turbulent air can make distant objects appear to twinkle or shimmer.
Does the atmosphere refract light?
Sunlight refracts as it travels from the vacuum of space into Earth's atmosphere. As its wavefronts graze the upper atmosphere, light bends downward (Figure 4). This means we see the Sun higher in the sky than it actually is.
What is reason for refraction of light in atmosphere?
The cause of the refraction of light is that light travels at different speeds in different media. This change in the speed of light when it moves from one medium to another causes it to bend. Refraction is caused due to the change in speed of light when it enters from one medium to another.
