and whats a negative refraction

Refraction is the bending of a wave's direction of propagation resulting from it propagating from one medium to another in which it has different phase velocity (propagation speed). Negative refraction is an unusual phenomenon in which the wave not only changes speed, but reverses direction too. This is not to be confused with reflection in which the wave changes direction, but stays in the first medium. It still goes into the new medium, but reverses direction nonetheless. It sounds paradoxical, but phase velocity can do funny things sometimes.

Whats A Refraction

In optics, refraction is when light enters a different medium and because of the change in optical 'density' the wave of light ( in this case light acts as a wave) changes it's speed and in turn its direction. I am not sure what you mean by negative refraction unless you are referring to 'Total Internal Refraction) which is when the difference in optical densities of the two mediums is so great, that the beam of light refracts at an angle which returns it to the original medium

Refraction refers to the bending of light when it goes through a lens.
