Question

(c) The refractive index of glass is 1.5. Calculate the speed of light in glass. The speed of
light in air is 3.0 x 108 m/s​

Answer 1

Answer:

2*10^8 m/s

Explanation:

Refractive index of glass = Spd. of light in air / Spd. of light in glass

=> 1.5 = 3*10^8/Spd. in glass

=> Spd. in glass = 2*10^8 m/s
