Light enters from air to glass, having a refractive index of 1.50. What is the speed of light in the glass? The speed of light in a vacuum is 3 x 108 ms-1.
Refractive index of a medium (nm) = Speed of light in vacuum(C) / Speed of light in the medium(V) Speed of light in vacuum (c) = 3 × 108 m/s Refractive index of glass (ng) = 1.50 Speed of light in the glass (v) = Speed of light in vacuum(C) / Refractive index of glass …
