What is transmission of light?

Light is transmitted through various mediums, including air, water, glass, and other transparent materials. When light passes through a material, it can be transmitted, absorbed, or reflected.

The transmission of light is dependent on the material it is passing through. Transparent materials, such as glass or water, allow light to pass through with minimal absorption or reflection. Opaque materials, on the other hand, do not allow light to pass through and absorb or reflect it instead.

The speed at which light is transmitted through a material is also affected by its refractive index. The refractive index is a measure of how much the speed of light is reduced when it passes through a material. Materials with a higher refractive index will slow down the speed of light more than materials with a lower refractive index.

Different colors of light can also be transmitted through materials differently. This is due to the different wavelengths of each color of light, with some wavelengths being more easily transmitted than others.

Overall, the transmission of light is a complex process that is influenced by the properties of the material it is passing through.
