statement?​

Answer 1

Explanation:

it means the diamond is most denser C

in which light refracted

Answer 2

Answer:

Explanation:refractive index is a deep concept.....

Basically when a wave enters a medium the electric field accelerates electron which produces electromagnetic waves.

The incident wave and new waves have different speeds, generally the new waves are slower.

The ratio of these two speeds is actually refractive index.

So when we say refractive index is 1.5 we mean that the incident wave is 1.5 times faster than the new electromagnetic waves
