You need refraction for increasing or decreasing the size of an image. We can take x-ray images just fine, and we don't have anything that will refract x-rays.
A ray with low index of refraction and greater velocity.
A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".A ray of light changes direction when it gets out of the water, and into the air.

terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
due to the phenomenon of refraction .
The ray is diffracted so that its path moves closer to the normal at the point of incidence.
A refracted ray passes through the medium, at a different angle to the normal than the incident ray. by Ronan Lavery
REFLECTION: IF a light ray in incident on a surface if it bring back to same medium is called reflection REFRACTION: IF a light ray in incident on a surface and going to another medium is called reflection and there is a a law for refraction that is SNELL'S LAW
