The speed of light is about 300,000 kilometers per second. Did you know that electrons that give electricity also travel very close to this speed. The information that travels on the internet also travels close to this speed. The information or modulated electrons travel in most conductors somewhere around 60% of the speed of light.
WiFi signals, which usually travel through the air, travel much closer to the speed of light than electrons moving through copper wire. These signals can travel at the maximum recorded speed of light in a vacuum, which is about 185,000 miles per second.
Certain calculations show that electrons can pass through a conductor at 90% of the speed of light. Imagine how fast these particles can travel in a vacuum. To make them travel faster, you need to use a lot more energy. This is because the electron gets a lot heavier as they reach the speed of light. However, light moves in space at 186,000 miles per second. Space is considered a vacuum. So maybe light waves are slowed down by friction. Your sunglasses can block UV light waves. In fact, many scientists believe that it takes certain types of radiation millions of years to escape from the center of the sun after millions of nuclear reactions.
The speed at which it travels is very dependent on the medium it travels through. Remember that there are materials through which light cannot move. Light can never pass through lead or different types of metal. The light particle, or waves, try to penetrate these materials. However, they only hit the outer surface and become kinetic energy. This means that they heat up the surface of these materials and disappear into thin air. Maybe they become potential energy. The laws of thermodynamics would indicate this. The first law of thermodynamics is known as the law of conservation. This law states that energy cannot be created or destroyed in a closed or isolated system. The second law of thermodynamics gives an interesting twist to the first law. The second law states that the entropy of any contained or isolated system is always increasing.
The speed of light is measured as 186,000 miles per second. The distance that information travels on the Internet is thousands of miles in seconds. In fact, the time it takes to receive information is in the blink of an eye. Of course, there are various devices that slow down the process such as routers and various types of switches. However, the process that slows down this method of information travel is how quickly people make decisions and feed their ideas onto the Internet. Human ideas can make the internet a good way to change the world. However, the internet can also be a method of conveying bad ideas.
Best wishes.
