Refraction Of Light

What is total internal reflection?

Total internal reflection is the phenomenon where light, traveling from a denser to a rarer medium, is completely reflected back into the denser medium when the angle of incidence exceeds the critical angle.

Why does light bend during refraction?

Light bends during refraction because it changes speed when it passes from one medium to another. The bending occurs due to the difference in optical densities of the two media.

What is the refractive index?

The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a given medium. It indicates how much light slows down in that medium.
