Why a speed of light changes causes refraction ... Plzz help me .. P..r..I..ty |

Answer» Light is slowed down in transparent media such as air, water and glass. The ratio by which it is slowed is called the refractive index of the medium and is usually greater than one. My question is why speed of light is changes when going to other medium ... Your answer is not clarify this clearly.. Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. |
