Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.
Electromagnetic Radiation is a spectrum that can be anything from Radio Waves to Gamma Rays. We use visible light to see, radio waves to send information, microwaves to heat food, infrared for sensors, UV damages our skin and is used in black lights, X-rays let us see bones, and Gamma Rays damage our body.
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.
- Radio Waves: Instant Communication.
- Microwaves: Data and Heat.
- Infrared Waves: Invisible Heat.
- Visible Light Rays.
- Ultraviolet Waves: Energetic Light.
- X-rays: Penetrating Radiation.
- Gamma Rays: Nuclear Energy.
In everyday life we encounter radio, microwaves, infrared, ultraviolet, and visible light waves. We usually don't experience X-rays, and very rarely gamma rays. Radio waves come from communication devices as well as interstellar radiation. Microwaves typically would be found in a microwave.
Examples are radio waves, microwaves, infrared radiation, visible light – (all colors of the spectrum that we see), ultraviolet light, X-rays and gamma radiation.
Hazards of electromagnetic radiation
- microwaves cause internal heating of body tissues.
- infrared radiation is felt as heat and causes skin to burn.
- X-rays damage cells causing mutations (which may lead to cancer) and cell death - this is why doctors and dentists stand behind protective screens when taking lots of X-rays.
Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation and radiation poisoning.
There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health. Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. And gamma rays can be used to kill living organisms, sterilize medical equipment, treat cancer, and take images using radioactive tracers.
Electromagnetic waves are ubiquitous in nature (i.e., light) and used in modern technology—AM and FM radio, cordless and cellular phones, garage door openers, wireless networks, radar, microwave ovens, etc. These and many more such devices use electromagnetic waves to transmit data and signals.
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial
List 5 examples of electromagnetic radiation. Visible light, X rays, ultraviolet, infrared light, microwaves, and radio waves.
This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.
The human is a electromagnetic field or is like a electron that come form the electromagnetic field . the photon is a electron magnetic field and it generates the electron and positron. The photon may also be a resultant of an electromagnetic field .
At low frequencies, external electric and magnetic fields induce small circulating currents within the body. The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health.
5 Tips to Safeguard Against Electromagnetic Radiation
- Disable Wireless Functions. Wireless devices — including routers, printers, tablets, and laptops — all emit a Wi-Fi signal.
- Replace Wireless With Wired Devices.
- Keep EMF Sources at a Distance.
- Use Your Smartphone Safely.
- Prioritize Sleeping Areas.
Detecting EM Waves. To detect the electric fields, use a conducting rod. The fields cause charges (generally electrons) to accelerate back and forth on the rod, creating a potential difference that oscillates at the frequency of the EM wave and with an amplitude proportional to the amplitude of the wave.
The wireless industry claims its technologies and levels of radiation are safe, while people around the world claim their health is negatively affected by electromagnetic radiation. Patients with EHS suffer a variety of symptoms from heart palpitations to migraines they claim are caused by radio frequency radiation.
Both tubes were jointly subjected to a weak electromagnetic field with 7Hz frequency. As mentioned in a recently published article in the New Scientist [2], 'physicists in Montagnier's team suggest that DNA emits low-frequency electromagnetic waves which imprint the structure of the molecule onto the water.
Advantages: In small quantities they help your body produce vitamin D. Disadvantages: They can cause sunburn or even skin cancer if used in large quantities. Visible Light: Visible light is the part of the spectrum you can see.
These waves have many uses which are vital to our daily lives: visible light allows us to see; microwaves and radio waves allow for long-range communication via mobile phones, television and radio; infra-red waves are used in night-vision cameras and in many remote controls; and x-rays are used in medical imaging; and
