Question

Light enters from air to glass having refractive index 1.5. The speed of light in glass
is​

Answer 1

Answer:

2*10^8 m/s

Explanation:

Refractive Index = Speed of light in vacuum/speed of light in the medium

1.5 = 3 * 10^8/speed of light in vaccum

Speed of light in glass

(3*10^8) / 1.5

2*10^8 m/s
