Question

The referactive index of glass is 1.5. Calculate
the speed of light in glass. The speed of light
inair is 3.0x10^8 ms^-1.​

Answer 1

Answer:

Step-by-step explanation:Speed of light in glass of refractive index 1.5

The speed of light in air is 3.0 x 108 m/s. 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 2

n=C/V

N=1.5

C=3.0x10^8 ms^-1.

Let's solve

V=C/n

Ans is

2x10^8 ms^-1.
