led sefraction of light.

Answer»

Refraction is a change on the direction of the light when pass from a medium to another one.Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on theindices of refractionof the two media and is described quantitatively bySnell's Law
