Question

Light enters from air to glass having refractive index 1.50. What is the speed of tight in glass? The speed of light in

vacuum is 3x10⁸ ms¹​

Answer 1

Answer:

refractive index of glass = speed of lightinvacuum/ glas

1.50= (3x10^8m/s)/ speed of light in glass

speed in glass= (3x10^8)/ 1.5

speed of light in glass = 2x 10^8 m/s

hope this is helpful
