Question

The refractive index of glass is 1.7. Calculate the speed of light in glass. The speed of light in air is 3.0 x 108 ms-1

Answer 1

Answer:

speed in glass = c/μ =3*10^8 /1.7 1.765*10^8m/s

Explanation:

Answer 2

Explanation:

We know that refractive index n

= speed of light in air/ speed of light in medium

where C = 3*10^8

1.7 = C/V

V =3*10^8/1.7

V = 1.764*10^8m/s
