Light ray enters from air to glass plate.what is the speed of light in glass if it refractive index is 1.5 ? |
| Answer» IVE index = 1.5According to laws of refractionRefractive index = SPEED of light in vacuum or air/Speed of light in the medium(GLASS)1.5=3*10^8 / speed in glassSpeed of light in glass =5 *10^7 | |
