Question

If the speed of light in the vacuum is 3*10 power 8 m/s .Find the speed of light in a medium with absolute refractive index 1.5

Answer 1

Answer:

200,000 kilometers per second in glass (refractive index of 1.5).

Answer 2

Answer:

Explanation:n=c/v

1.5=3×10^8/v

v=3×10^8/1.5

v=2×10^8m/s
