Question

light enters from air to glass having refractive index 1.50. what is the speed of light in the glass? The speed of light in vacu00um is 3 10 to the power 8 metre per second?

Answer 1

Hii friend,

Here is your answer_______________

Hope this helps you a little!!!

Answer 2

Refractive Index = Speed of light in vaccum/speed of light in medium

1.5 = 3×10^8/speed of light in glass

Speed of light in glass
= (3×10^8)/1.5
= 2× 10^8 m/s.
