Question

find the speed of light in glass if the refractive index of glass is 1.5 and c= 3×10​

Answer 1

Refractive index of glass = 1.5

Speed of light in air = 3.0 x 108 m/s

We know that

Refractive index of glass = speed of light in air/speed of light in glass

1.5 = 3 x 108/speed of light in glass

Speed of light in glass = 2 x 108 m/s

hope it helps you...
