What is an electromagnetic frequency?
Electromagnetic frequency is a measure of how many times the top of the wave passes through a particular point. It is measured in Hertz, which can also be written as a simple "per second". The frequency of the wave is one of its most basic principles and the extent of possible frequencies is something known as an electromagnetic spectrum. It runs from low -energy radio waves to high energy gamma rays. Unlike its wavelength, the electromagnetic frequency of the wave does not change. It is a transverse wave, which means it oscillates up and down in the direction of which it moves. The electromagnetic frequency of the wool is defined as how many times the peak of this oscillation moves around the point every second. This has the main effect on the properties of the wool, including its energy. On the other hand, the wavelength is the distance between the two vertices of the wool or in the other word, the length of the full cycle. For example, low -frequency electromagnetic waves have a small amount of energy and are therefore relatively safe. This is more oftenKnown as radio waves. Low -frequency waves such as radio waves and microwaves have long wavelengths.
If the electromagnetic frequency of the wool is high, then the wool carries a large amount of energy. On the contrary, the wavelength of the wool in this situation is very short. X -rays and gamma rays are two examples of high electromagnetic frequency waves, and therefore these types are dangerous when people are exposed to them. Visible light is also a type of electromagnetic wool with frequency somewhere around the center of the electromagnetic spectrum.
When the wave goes from one medium to another, for example, air into water changes the direction as a result of a phenomenon known as quarry. This is because the wool changes the speed when entering the material with a different density. A common mistake is to assume that it changes the electromagnetic frequency of the wool. This is not the case, because the frequency of the wool remains the same regardless of the medium. It will change the waveletlength and speed of the wool, resulting in a slower wave of the same energy.
