What is electromagnetic radiation and how does it work?
This type of radiation derives from what our eyes perceive as a clear, observable field of view. We receive EM radiation as information over various wavelengths and frequencies through waves or particles, which ultimately form the electromagnetic spectrum.
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.

How are electromagnetic waves emitted?
Electromagnetic waves are emitted by electrically charged particles undergoing acceleration, and these waves can subsequently interact with other charged particles, exerting force on them.
Can humans emit electromagnetic waves?
Yes, all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Such radiation is sometimes called thermal radiation. Most of the radiation emitted by human body is in the infrared region, mainly at the wavelength of 12 micron.

Electromagnetic waves are waves that consist of vibrating electric and magnetic fields.
What are the two main sources of electromagnetic waves?
Sources of Electromagnetic Radiationsolar radiation, in other words natural radiation that originates from the sun.terrestrial radiation, in other words natural radiation emitted by the Earth's surface.artificial radiation originating from a remote sensing system.
How do electromagnetic waves propagate through space?
An electric and magnetic field have no need a medium to show thier effect. Hence in the presence of electric and magnetic field vector which vibrate perpendeculer to each other and get pertervation EM waves travels in vacuum. Show activity on this post. Electromagnetic waves are only an observed phenomenon.

What are some examples of electromagnetic radiation?
Here are 10 examples of electromagnetic radiation which we come across daily and the harmful effects that result from it: 1. Visible Light Waves. Let’s start with the most visible type of electromagnetic radiation: visible light waves. This type of radiation derives from what our eyes perceive ...
Why are microwaves used in space?
Because they have a low frequency and long wavelength, they can penetrate clouds, smoke and rain easier than visible light waves. This is one of the main reasons why microwaves are used to transmit signals into space orbit.
What happens when you heat up a microwave?
When you heat your meal in a microwave oven, the water molecules absorb microwave radiation and generate a thermal increase that also kills any present bacteria. Since the only form of energy transmitted to your food is heat, there is a minimal risk of contamination or radiation that can affect your health.
What is the name of the radiation that is emitted from a TV remote?
Infrared Waves. Infrared waves are set somewhere between visible light waves and microwaves. Some of them are slightly visible in everyday life, such as the one emitting from your TV remote or the smoke detector, which are virtually harmless. This type of radiation is called “near infrared waves. ”.
What happens if you are exposed to thermal radiation?
Long-term exposure increases thermal radiation and may trigger headaches, vision problems, sleep disruption and even memory loss.
Why do gamma rays kill cancer cells?
Their cell-penetrating power is the reason why gamma rays are sometimes used to kill cancer cells. Some clinical tests revealed that the destructive force produced by gamma radiation can alternatively repair genetic material.
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 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 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 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.
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 the biggest radiation?
According to the EPA, the largest radiation dose received by the public (after radon) is from smoking cigarettes. Cigarette smoke contains small amounts of radioactive materials, which smokers bring into their lungs as they inhale.
What agency regulates radiation?
Radiation from products, including cellphones and smart meters, is regulated by a combination of state and federal agencies, including the Environmental Protection Agency (EPA). These regulations are put in place to protect the consumer.
What is the radioactive isotope used in smoke detectors?
Smoke detectors. According to experts, some household smoke detectors use small amounts of radioactive isotope, americium-241, to alert you when there is smoke in the air. The detector does not pose any health risks because the material is surrounded by ceramic and foil.
Does radon cause lung cancer?
Radioactive particles (most radon progeny) lodge in lung tissue and, over time, contribute to a larger radiation dose. Radioactivity is one of the key factors in lung cancers among smokers, the EPA writes.
Does phosphate fertilizer contain radium?
According to the EPA, phosphate fertilizers contain some of the naturally occurring radium found in phosphate ores.
