Question

hi friends
what is the refractive index of rock salt
plz make it fast​

Answer 1

Explanation:

Absolute Refractive index =n=Speed of light in vacuum/Speed of light in medium

n=C/V

So The refractive index of Rock salt is 1.54 That means

1.54=Speed of light in vacuum/Speed of light in Rock salt

So, Speed  of light in Rock salt is 1/1.54 times speed of light in vacuum.

Therefor Speed of light in Rock salt is  less [1.94 x 10⁸m/s ] compared to speed of light in vacuum =C = 3 x 10⁸ m/s.

Hope it helps you....
