Question

The speed of light in a medium is 2×10^8m/s.Find it's refractive index​

Answer 1

Answer:

The velocity of light in vacuum is 3.00 • 10^8m/s, and the speed of light in glass as given, converted to meters is 2 • 10^8m/s, hence the refractive index of glass is 3/2 or 1.5 (10^8 cancels out).
