Question

Refractive index:-
1.) wavelength of light used
2.) is the actual property of a substance
3.) depends on angle of incidence
4.) None of these

Answer 1

Answer:

none of these

Explanation:

answer is none of them

Answer 2

Answer:

Answer :-

It is the actual property of a substance

Explanation :-

The actual property of any substance is compared with the speed of light in vaccum space.

The formula for finding refractive index is

ng = c/v

ng is the refractive index

c is the speed of light in glass

v is the speed of light in vaccum space
