Question

The absolute refractive index of water is 1.36. What is the velocity of light in water? (velocity of light in vaccum 3×10tendas to 8 m/s

Answer 1

hey buddy,here is ur ans! .. hope that u will understand!

Answer 2

Explanation:

=Uw= 1.36

=Vw=?

=Ve=3× 10^8

=Absolute refractive index= Uw / Ue = Ve / Vw

1.36/1 =3×10^8/ Vw

=3×10^8 / 1.36

=2.2 × 10^8.
