Radio waves, microwaves, X-rays, and gamma-rays are some of the types of radiation that is around us. The visible light is only a small portion of the spectrum, which contains a broad range of wavelength.
Gary Bedrosian, a physicist at the Rensselaer Polytechnic Institute in Troy, New York, said that people have known about electricity and magnetism since ancient times, but the concepts were not well understood until the 19th century. According to Live Science sister site Space.com, Scottish physicist James Clerk Maxwell developed a unified theory of electromagnetism after showing that the two phenomena were connected. The study of electromagnetism deals with how particles interact with each other.
The different interactions of electricity and magnetism were described by a set of formulas. Initially there were 20 equations, but later they were simplified to four basic ones. The equations state the following:
An electric field causes a charged atomic particle, such as an electron, to move. According to an online physics and astronomy course, the movement produces magnetic and electric fields that travel at right angles to each other. The waves have certain characteristics.

A wavelength is the distance between two peaks of a wave. The distance is given in meters or fractions. The number of waves is Frequency. The number of wave cycles per second is known as the hertz. One cycle can pass in a shorter amount of time if the wavelength is short. Each cycle takes longer to complete, so a longer wavelength has a lower Frequency.
There is an enormous range of frequencies and wavelength. According to UCAR, this range is known as the electromagnetic spectrum. The spectrum is divided into seven regions in order of decreasing wavelength and increasing energy. Radio waves, microwaves, IR, visible light, UV, X-rays, and gamma-rays are all common.
The lowest range of the spectrum is 30 billion hertz, or 30 gigahertz, and the wavelength is less than 10 millimeters. Data and entertainment media are some of the things radio is used for.
The range of the spectrum between radio and IR is where microwaves fall. They have frequencies from 3 GHz to 30 trillion hertz, or 30 Terahertz, and wavelength from 0.1 to 10 millimeter. Microwaves are used for high-bandwidth communications and radar, as well as for a heat source for microwave ovens and industrial applications.
The range of the spectrum is between microwaves and visible light. IR has frequencies from 30 to 400 THz and a wavelength from 3 to 4 inch. IR light is invisible to human eyes, but we can feel it if the intensity is enough.
The visible light is in the middle of the spectrum. It has frequencies of 400 to 800 THz and a wavelength of 15 to 0.00003 inch. Most human eyes can see the wavelengths that are visible to visible light.
The range of the spectrum between visible light and X-rays is called the ultraviolet light range. It has a range of frequencies from 8 to 14 to 3 to 16 and a wavelength from 0 to 15 inch. UV light is invisible to the human eye. It can damage living tissue, but it has many medical and industrial applications.
Soft X-rays and hard X-rays are the two types of X-rays. The range of the spectrum is made up of soft X-rays. Soft X-rays have frequencies of 3 to 10 16 and a wavelength of 4 to 4. The same region of the spectrum is occupied by hard X-rays. The only difference between them is their source.
Soft X-rays are in the range of the spectrum. There are more than 10 18 hertz and less than 4 th of an inch of wavelength in the radiation. It's useful for killing cancer cells when applied in carefully measured doses to small regions because of the damage it causes to living tissue. Uncontrolled exposure is dangerous to humans.
