Before going...... can anyone help me with refractive index.........

Please explain it ! ​

Answer 1

Answer:

${\huge{\mathfrak{\underbrace{\pink{Answer}}}}}$

.

The refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n=c/v.

I hope this helps you siso.....

Answer 2

Answer:

the ratio of the velocity of light in a vacuum to its velocity in a specified medium.

Explanation:

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
