Question

what is refractive index?​

Answer 1

Answer:

formula:-

n=\frac{c}{v}

n = refractive index

{c} = speed of light

{v} = phase velocity of light

Explanation:

In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. It is defined as refrective index

Answer 2

Answer:

kya problem hai kya kal se pin pe nahi aye hamse naraj ho.

ya fir exam shuru hogagi.
