Question

light enters from air to glass having refractive index 1•50 what is speed of light in glass the speed of light in vaccum​

Answer 1

Answer:

Speed of light in vaccum , C = 3 * 10^8 m/s

Refractive index, n = 1.50

Speed of light in glass, V = ?

n = V/C

V = n * C

V = 1.50 * 3 * 10^8 m/s

V = 4.5 * 10^8 m/s
