Question: What are 3 things that travel in cycles? What causes light to break into recognizable patterns while passing through a thick layer of smoke? What causes the sound to vibrate and what exactly is the frequency? These, and several other questions come to mind when one considers traveling in a wave. The answers are both simple and complex, but hopefully, they will help you decide if traveling in a wave is for you!
Firstly, we need to look at the waves. Light, in itself, is a wave. While this may not mean much to you at first glance, but it does mean a lot when trying to understand light. Light is composed of little packets of energy known as photons, each of which can be in one of four states: red, green, yellow, or blue. These are in addition to the usual color of light, which is white.
Things That Travel
Photons travel in a predictable fashion when in a wave-like sound – but they travel in cycles. For example, a light bulb will generate light in one state, and then release it in another state. In the next cycle, the bulb will be back to generating light in the original state, but in the next cycle, it will be emitting light in the same state. This is why we can see a faint glow of light from behind a building even though there is not a beam of light being reflected on the ground – the light has just traveled through the air.
As you have probably guessed, light can only move in a single cycle. We can see objects that we see through the eyes of humans, but objects far away appear as flashes of color. The reason for this is that light is composed of many tiny packets of energy, each of which has its own wavelength. When we use binoculars, we can view objects that are close to our eye, but objects further away appear as swirls of light – these are because the waves of light are being absorbed by the atmosphere. The farther away from the object, the longer the wavelength of the light that is being reflected back.
Light is a good conductor of heat. A bulb can emit light of a high temperature and so can a traveling wave. A metal tube that absorbs heat is called a reflector and is used to send information from one computer to another over long distances. When traveling through a vacuum, things that travel faster than the speed of light tend to absorb all the heat that is produced. The corona discharge is caused by electrons, traveling faster than the light, heating the surrounding matter.
A Much Ado
One of the reasons that things that travel faster than the speed of light often come into contact with each other is because they are moving at the same time. Imagine what happens when you rub your hand against a hot radiator. If you placed your hand directly on the surface of the radiator without touching any of the internal parts, your hand would not absorb the heat. Your hand would simply pass through the whole thing. Because of this, you will feel cold before you feel hot and it will take longer for the heat to leave you than if you were just standing directly in front of the radiator without touching it.
In our case, the “fast” things that travel faster than light include the radio and television signals that we receive. These signals are so fast that they are absorbed by many objects before they reach us. Although they are traveling through fewer molecules than the light rays, they are still extremely hot. Thus, they cause us to feel the chill before we sense the heat.
One of the great advantages of space traveling is that we don’t have to return all of the things that travel faster than light. Any energy that we use in order to travel faster than the speed of light comes from something we already have on Earth. Thus, the amount of energy needed to travel to other places is significantly less than it would be to send the same amount of energy through microwaves or lasers. This makes long-distance travel a lot easier and cheaper. Just think about the cost of all the fuel that would be required to send cargo in spaceships and how much it would cost to build starships that could easily carry people and cargo to far-off places.
