Answer:
What is the speed of light in the glass? The speed of light in vacuum is 3 x 108 ms-1. =3 — 108/1.50 = 2x 108 ms-1.

Answer:
Refractive index of a medium (nm) = Speed of light in vacuum/Speed of light in the medium
Speed of light in vacuum (c) = 3 × 108 m/s
Refractive index of glass (ng) = 1.50
Speed of light in the glass (v) = Speed of light in vacuum/ Refractive index of glass
= c/ng
=3 × 108/1.50 = 2x 108 ms-1.
