Question

Drfine refraction and refraction index​

Answer 1

Answer:

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.

Answer 2

Answer: it is refractive index not refraction index

Explanation: The phenomenon of bending of light is called refraction.

refractive index= (mu)=speed of light in vacuum/speed of light in a medium
