The speed of light in air is around 299,705 kilometres per second or2.99705×108m/s. Light travels at a constant speed of... Learn more about this topic: Refraction & Dispersion: Definition, Snell's Law & Index of Refraction from
The light travels as a wave with a definite speed. This speed varies if the medium of travel changes in its path. The speed of light gets slower if the medium is denser. The fastest speed of light is in the vacuum, c=3×108 m/s ...
To calculate the speed of light in glass, we can use the relationship between the speed of light in different media and the refractive index. The refractive index (n) is defined as the ratio of the speed of light in a vacuum (or air, approximately) to the speed of light in the medium...

We must, however, make an assumption about the speed of light in water. We shall assume that the speed of light in water is lower than the speed of light in air by a certain factor, n . Fig. 26–4. Illustration of Fermat’s principle for refraction. In Fig. 26–4, our problem ...
Is the speed of light constant? The speed of light is a universal constant in a vacuum, like the vacuum of space. However, light *can* slow down slightly when it passes through an absorbing medium, like water (225,000 kilometers per second = 140,000 miles per second) or glass (200,...
