Light Is Traveling Through The Different Media Shown. In Which Medium Does Light Travel Fastest?


What medium does light travel through faster than air?

Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second.

Which medium does light travel slowest through?

The higher the index of refraction is, the slower the speed of light is. The indexes of refraction for diamond, air and glass are, respectively, 2.42, 1.00, and approximately 1.50, depending upon the composition of the glass. Light travels slowest in diamond.

What medium does light travel through?

Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.)

Why speed of light is different in different medium?

Speed of light does not change, it has to travel more in a medium than in vacuum, When light is passing through a medium, the electrons in the medium absorbs the energy from the light and gets excited and releases them back. This absorption and re emission of light gives objects colour.Travel
