The speed of light in a material medium is slower than the speed of light in a vacuum. This is a consequence of the electromagnetic wave interacting with the atoms and molecules in the medium, a process merits its own question.Of course, this assumes the medium is transparent for the wavelength of light travelling through it.Light waves slow down when they pass through a medium, eg glass or water
Electromagnetic radiation travels at a speed that's not only faster than any other wave,but is also the "universal speed limit", faster than which nothing can move.
it is speed
Time is relative to the speed of the observer and the faster an observer travels at the slower time will appear for him. So time slows down with speed not with distance.
Light in a vacuum is represented by a constant known as c=2.99792458 m/s. Otherwise I can recommend two books called general relativity and special relativity both written by our very own Albert Einstein.
wave speed
The speed at which a wave travels through water or another medium is called the wave speed. It is determined by the properties of the medium, such as its density and elasticity.
The speed at which a wave travels through a medium is called the wave speed or wave velocity. It is determined by the properties of the medium, such as its density and elasticity, and is independent of the wavelength and frequency of the wave.
The material through which waves travel is called a medium. The properties of the medium, such as density and elasticity, influence the speed and behavior of the wave as it propagates through the medium.
The medium in which it travels through
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
The material through which a wave travels is called the medium. Waves can travel through different mediums, such as air, water, or solid materials like metal. The properties of the medium, such as its density and elasticity, can affect the speed and behavior of the wave.
Sound is affected by the media. It travels high speed in solids generally.

Over 6,000 mph.
The speed at which a wave travels through a medium depends on the properties of the medium. In general, the denser the medium, the faster the wave will travel. The speed of a wave can also be influenced by factors like temperature, pressure, and elasticity of the medium.
