a mirage
The image of a distant object is brought into focus in front of a person's retina, the defect is called nearsightedness. A virtual image produced by a lens is always located in front of the lens.
the bending of light when passing through an object
This effect is called a 'Mirage.' It occurs when the light rays from a distant object are refracted by heated air so that the object appears to be nearby.
It is the most distant object known
Well a rainbow is just a refraction of the sun's light caused by water molecules in the air. Yo do not need rain to see a rainbow-like object, but you definitely need the sun.
That is called refraction.

It's called refraction.
reFRACtion There isn't a good nmeonic or the like to remember the difference between refraction, reflection and diffraction. You just have to learn it.
Refraction of light allows for the change of appearance of an object
Distance objects can be seen to "ripple" on a hot day because of refraction. As light from a distance object makes the trip to the observer, it passes through air of slightly varying densities. This causes it to "change course" to a degree, which is refraction. It is this thermally induced refraction that is responsible for the "ripple" we see, and for the mirage we sometimes hear about.
The bending of a wave as it moves from one medium into another is called refraction.
it changes the direction of light
because of refraction , you see the object "bending"
