The speed of light about 300 000 kilometers per second. Did you know the electrons, giving the use of electricity, and travel very close to this speed. Information that travels over the Internet, also traveling at such a speed. Information or modulated electrons fall somewhere around 60% the speed of light in most conductors.
WiFi signals that travel primarily by air travel is much closer to the velocity of light than the electrons moving through the copper wire. These signals can travel with the maximum recorded speed of light in vacuum, which is approximately 185,000 miles per second.

Certain calculations show that electrons can move through the conductor at a speed of 90% of light. Imagine how soon these particles can travel in vacuo. To make them go faster, you need to apply a lot more energy. This is because the electron becomes much harder as they reach the speed of light.

However, the light in space is moving at a speed of 186,000 miles per second. Space considered in vacuo. So maybe light waves are slowed down by friction. Your sunglasses can block UV radiation. In fact, many scientists believe that in order to release the center of the sun after millions of nuclear reactions, need certain types of radiation.
The speed with which moves, is very dependent on the environment, which it moves. Consider whether there is a material through which light can not move. Light can never go through a lead or a different kind of metal. A part of the light wave, or try to penetrate these materials. However, they get only the outer surface and acquire kinetic energy. This means that they heat the surface of these materials are dispersed in anything. Maybe they are a potential energy. The laws of thermodynamics indicate that. The first law of thermodynamics is known as the law of conservation. This law states that energy can not be created or destroyed in a restrained or isolated system. The second law of thermodynamics is an interesting twist of the first law. The second law states that the entropy of any information contained or isolated system always increases.
Measured the speed of light at 186,000 miles per second. The distance that the information held on the Internet, thousands of miles per second. In fact, the time required to obtain the information comes in an instant. Of course, there are various tools that slow down the process, such as routers and various types of switches. However, a process that slows down this process the information travels – is how quickly people make decisions and are able to contribute their ideas on the Internet. Human ideas can make the Internet a good way to change the world. However, the Internet can also be a method of transmission of evil ideas.
