Is this Jeopardy? OK I'll bite = "What is...a mirage?"
a mirage
You're going for "mirage", but we're not comfortable with that description. It's not really the "image" that's caused by refraction. It's more the location or direction in which the image is seen that's caused by refraction.
Mirage
the difference between refraction and reflection is that in refraction light bends and in reflection it is reflected
If the surface is shiny then you might get an image on a screen. If the surface is transparent as well then refraction well also take place.
Without refraction, lenses would not be able to magnify an image.
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
It is involved in Refraction.
refraction
The refraction of light by the cornea and lens of the eye makes it possible for an image to form on the retina. Without the formation of an image, it would be possible for the retina to detect the presence or absence of light, but not shapes or objects.
As light hits the water it is slowed down. As the light above the water is going at 3x108 m/s, and the light in the water is going considerably slower, the image of the pencil looks like it is split in two. This is called 'refraction'.
