How electromagnetic radiation occurs?
Electromagnetic radiation occurs when an atomic particle like an electron, is accelerated by an electric field, causing it to accelerate.
What is Electromagnetic Radiation?
Electromagnetic radiation is the propagation of energy, in the form of light, through space. Much like ocean waves transfer energy through water, electromagnetic waves transfer energy through an electromagnetic field. Electromagnetic radiation travels in packets of energy called photons, and the energy in each photon depends upon the wave's frequency (but not amplitude). The radiation is created by the motion of charged particles and includes seven types: including radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays. It is important to note that visible light is not fundamentally different from the other six types, except for the fact that it can be detected by the human eye.
What is the least dangerous type of electromagnetic radiation?
Radio waves are low-frequency, long-wavelength electromagnetic waves. They are the least energetic and least dangerous type of electromagnetic radiation. Their wavelength is defined as any wavelength above 1 millimeter, and their frequency is defined as any frequency below 300,000,000,000 Hz. Radio waves are used for everything from car stereos to cell phones to garage door openers.
What is the wavelength of infrared light?
Infrared wavelengths are defined as any wavelength between 25 micrometers and 2.5 micrometers , and their frequency is defined as any frequency between 10,000,000,000,000 and 400,000,000,000,000 Hertz. Infrared light is created by heat lamps, toasters, and even ovens to heat our food. Although, one should note that these devices can also create visible light when they are turned up to a high enough setting.
What is the difference between visible and ultraviolet light?
However, one key difference between ultraviolet light and visible light is that ultraviolet light can be dangerous. At high frequencies and high amounts, ultraviolet light is capable of stripping electrons from the materials it strikes. This can damage human cells and tissues, causing sunburns and worse. The wavelengths for ultraviolet light vary from 1 to 400 nanometers, and the frequencies are between 1,000,000,000,000,000 and 100,000,000,000,000,000 Hertz.
How many categories are there in the electromagnetic spectrum?
This ranking includes seven categories, listed in order as follows:
How does electromagnetic energy travel?
The energy travels at the speed of light (in fact, it is light!) in a vacuum, but travels slower through a medium. It can be emitted from objects, reflected by objects, or absorbed by objects. In the case of emission, the motion of charged particles within an object typically creates the wave (imagine the hot filament in a lightbulb). In the case of reflection, the wave bounces off a surface (imagine a mirror). And in the case of absorption, the wave is absorbed by an object and the charged particles within the object begin to move faster (imagine pavement absorbing sunlight on a hot day).
Why are X-rays important?
But they are also very useful. Because X-rays penetrate soft tissue more easily than bones, doctors use X-rays to identify fractures and assess many diseases. It is important that they are used safely, however. Typically, X-rays machines are turned on for only a brief moment and one's internal organs are shielded from the procedure using a lead blanket or something similar. The wavelengths for X-rays range from 1 nanometers to 1 picometer, and the frequencies are between 100,000,000,000,000,000 and 100,000,000,000,000,000,000 Hertz.
What is Electromagnetic Radiation?
Electromagnetic radiation can be defined as a form of energy that is produced by the movement of electrically charged particles travelling through a matter or vacuum or by oscillating magnetic and electric disturbance. The magnetic and the electric fields come at 90° to each other, and the combined waves move perpendicular to both electric and magnetic oscillating fields occurring the disturbance.
What are the properties of electromagnetic waves?
Then based on the wavelength of the electromagnetic spectrum, the energy is grouped into different categories. These magnetic and electric waves travel perpendicular to each other and have some characteristics like wavelength, amplitude, and frequency. Some basic properties of Electromagnetic Radiation are given in the points mentioned below.

Electromagnetic radiation is a form of energy that is present all around us and takes various forms like microwaves, television waves, radio waves, gamma rays, X-rays, etc. In this piece of article, we will discuss electromagnetic radiation and its properties.
What is the wavelength of a wave?
Wavelength (λ) is the distance between successive crests of a wave, especially points in an electromagnetic wave or sound wave. It can be simply defined as the distance of one full cycle of the oscillation. If ‘λ’ is the wavelength, ‘c’ is the speed of light and ‘ ν ‘ is frequency. Then we can derive the relation given below.

What are some examples of electromagnetic radiation?
Electromagnetic Radiation Examples. Example 1: Gamma Rays. Gamma rays are generated by nuclear fusion reactions on the sun or radioactive decay of uranium in the earth's crust. Gamma rays are extremely high energy waves produced by nuclear reactions. Example 2: X-Rays. X-Rays used by dentists and doctors for diagnosis.

Why does a warm body emit radiation in the infrared region?
A warm body, like yours, emits, radiation in the infrared region due to its temperature.
How are low energy waves picked up?
These low energy waves are picked up by radio tuners, which can be set to pick up radio waves of specific frequencies.
What is the most energetic form of electromagnetic radiation?
Gamma rays are the most energetic form of electromagnetic radiation. It is ionizing radiation with a wavelength below 0.01 nm that arises from nuclear phenomena, by de-excitation of a proton or neutron. Astrophysical events of great violence (such as a supernova) emit this form of gamma radiation. Fortunately, the Earth’s atmosphere absorbs these radiations. In the clinical setting, this radiation is used for diagnostic processes and, ironically enough, the treatment of certain types of cancer.
What are the two types of radiation?
The main differentiation is made into two groups: non-ionizing radiation (radio waves, microwaves, infrared, and visible light) and ionizing radiation (ultraviolet , X-rays , and gamma rays). Let’s see the characteristics of all of them.
What is visible light?
Visible light is a type of non-ionizing radiation with a wavelength between 780 nanometers and 380 nanometers. The visible spectrum is a narrow band in which the only form of radiation that our eyes are able to see is found.. Color is light and light is basically electromagnetic waves that travel through space and reach our eyes.
What is the wavelength of infrared light?
Infrared is a type of non-ionizing radiation with a wavelength between 15,000 nanometers and between 760 and 780 nanometers., thus limiting the red color of visible light. Hence it is known as infrared. We humans emit this form of radiation. Night vision equipment uses infrared detectors, as it allows you to see bodies based on their thermal properties. Remote controls, fiber optic cables, and infrared telescopes also rely on this form of radiation.
What is non ionizing radiation?
Non-ionizing radiation is that form of electromagnetic radiation emitted by less energetic bodies. It is therefore based on electromagnetic waves of low energy, low frequency and high wavelength. Unlike ionizing ones, they are not capable of removing electrons from the atoms of the matter on which they impinge. It is the fringe of the electromagnetic spectrum that spans radio waves, microwaves, infrared, and visible light.
What is the electromagnetic spectrum?
In this context, the electromagnetic spectrum is the radiation that a substance emits or absorbs and ranges from radiation with a longer wavelength, radio wave radiation, to that of a shorter wavelength, such as gamma rays. And in between, we have, for example, visible light, which is another form of electromagnetic radiation.
What is microwave radiation?
Microwaves are that type of non-ionizing radiation with a wavelength between 10 millimeters and 1 meter.. This range is included within the radio frequency bands, specifically the ultra high frequency bands. Be that as it may, one of the best known applications is that of microwave ovens, which generate this radiation which, although it is not ionizing, is capable of vibrating the water molecules present in food. And from this vibration, heat arises.
