Electromagnetic radiation examples: Electromagnetic energy is a term used to describe all the different types of energies that releases from the different objects that exist on the earth. These kinds of energies include some that you will recognize and some that will sound strange and some are invisible. They include:
Electromagnetic radiation examples as following
- Radio Waves
- TV waves
- Radar waves
- Heat (infrared radiation)
- Ultraviolet Light
- Gamma waves
All these waves have different properties and do different things. for example, heat waves make molecules move and warms the things, while light waves make things visible to the human eye and x rays can pass through a person and land on film, that allowing us to take a picture inside someone’s body.
They travel in waves, like the waves at a beach or like sound waves, and waves that are also made of tiny particles. The difference between transverse and longitudinal waves.
It is a type of electromagnetic radiation with wavelengths longer than infrared light in the electromagnetic spectrum. Radio waves have frequencies as high as 300 GHz to as low as 30 hertz (Hz). Examples of radio waves in everyday life? The corresponding wavelength is 1 mm at 300 GHz, and 10,000 km at 30Hz.
Like other electromagnetic waves, radio waves also travel at the speed of light in vacuum. They are generated by electric charges when they accelerate, such as time varying electric currents. In naturally radio waves are emitting by lightning and astronomical objects.
Radio waves are artificially generated by transmitters and received by radio receivers, by using antennas. Radio waves are widely used in modern technology and mobile radio communication, broadcasting, radio navigation and radar systems, communications satellites, wireless computer networks, and many other applications.
Different frequencies of radio waves have different propagation characteristics in different mediums; long waves can diffract around the obstacles like mountains and follow the contour of the earth, shorter waves can reflect off from the ionosphere and return to the earth beyond the horizon, while shorter wavelengths beam bend or diffract very small and travel on a line of sight, so their propagation distances are limited. Difference transverse and longitudinal waves?
TV waves are also known as Infrared Waves that are on the electromagnetic spectrum at wavelengths much longer than those of visible light waves but shorter than those of radio waves. Their wavelength is about 3 meters or 10 feet.
A detection system that uses radio waves to determine the range, angle, or velocity of objects is called radar waves. It can be used for the detection of aircraft, ships, motor vehicles, weather formations, spacecraft, and guided missiles.
Heat (infrared radiation)
Infrared radiation sometimes called infrared light. These electromagnetic radiations have wavelengths longer than visible light. Therefore it is invisible to the human eye, although Infrared radiation at wavelengths up to 1050 (nm)s, especially pulsed lasers can be seen by the human’s eyes under certain conditions.
Infrared radiation is generated or absorbed by molecules when they change their rotational-vibrational movements.
It excites the molecule in the vibrational modes through change in the dipole moment, that’s make it useful frequency range for study of these energy states for molecules of the symmetrical proper. The Infrared ray spectroscopy examines absorption and transmission of photons in the infrared range.
Infrared radiation is utilized in mechanical, law authorization, military, logical, and medicinal applications.
Light is a typical transverse, electromagnetic wave that can be seen by the human eye. The wave nature of light was first introduced through experiments on interference and diffraction. Light can travel through a vacuum. The transverse nature of light wave can be demonstrated through polarization.
Light is produced by two methods…
It is the emission of light from hot matter (Temperature ≳ 800 K).
It is the discharge of light when energized electrons tumble to bring down vitality levels
(in issue that could possibly be hot).
- The speed of light in a vacuum is a universal constant in all different frame of reference.
- The speed of light in a vacuum is fixed about 299,792,458 m/s.
- The speed of light in a medium is slower as compare to the speed of light in a vacuum.
- The speed of light depends upon the medium through which light is travel. The speed of anything having mass is always less than the speed of light in a vacuum.
It is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for sunburns. However, too much intensity of Ultraviolet radiation is damaging living tissue.
Electromagnetic radiation that comes from the sun and transmitted in the form of waves or particles at different wavelengths and frequencies. Types of uv radiation? This range of wavelengths having different frequency is known as the electromagnetic spectrum.
This spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency of the wave. The common designations are infrared rays, radio waves, microwaves, visible light, ultraviolet radiation, X-rays and gamma-rays.
X-rays are the electromagnetic waves and its range of wavelengths is 0.01 to 10 nanometers and energies is in the range of 100 eV to 100 keV.
They are shorter in wavelength as compare to ultraviolet rays and larger than gamma rays. In other many languages, X-radiation is called Rontgen radiation, after Wilhelm Rontgen, who is discoverer of X-Rays, and named it X-radiation to signify an unknown type of radiation.
these are electromagnetic waves with wavelengths ranging from one meter one millimeter, or equivalently with frequency between 300 MHz (0.3 GHz) and 300 GHz.
The microwave region of the electromagnetic spectrum is generally considered to overlap with the highest frequency having shortest wavelength is radio waves.
In all electromagnetic waves, microwaves travel in a vacuum with the speed of light. The prefix “micro” in “microwave” is not only meant to suggest a wavelength in micrometer range.
It indicates that microwaves are so small because of shorter wavelengths as compared to waves that used in typical radio broadcasting.
A gamma wave is a pattern of neural oscillation in human body with a frequency between 25Hz and 100 Hz, 40 Hz is typical. Examples of electromagnetic waves in everyday life? According to a popular theory, gamma waves may be implicated for creating the unity of conscious perception.
