The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
What is the difference between microwaves and ultraviolet light?
Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. … The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry.
How are microwaves different from other waves?
Microwaves travel by line-of-sight; unlike lower frequency radio waves they do not diffract around hills, follow the earth’s surface as ground waves, or reflect from the ionosphere, so terrestrial microwave communication links are limited by the visual horizon to about 40 miles (64 km).
What is the difference between microwaves radio waves and gamma rays?
They’re just waves of energy travelling through space — or through things. The only difference between gamma-rays from nuclear bombs and the waves that let our TVs and microwaves do their thing is how much energy those waves have got. Radio waves have got the lowest energy on the electromagnetic spectrum.
What’s the difference between radio waves and ultraviolet waves?
The two wave types has the same speed in vacuum which is equivalent to 3.00x108m/s. The difference is that radio waves have lower frequency but longer wavelength than the ultraviolet waves.
Which waves can be seen by the eye?
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength.
Do microwaves have radiation?
Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays. … But the most common consumer use of microwave energy is in microwave ovens.
What are the 7 types of electromagnetic radiation?
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.
Which electromagnetic has the highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
What is the most important electromagnetic wave?
The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves.
Which wave has lowest frequency?
Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV.
What does M stand for in electromagnetic spectrum?
|Micro- waves and radio waves||MF||Medium frequency|
|VLF||Very low frequency|
|ULF||Ultra low frequency|
How do we use radio waves in everyday life?
They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys. (For a fuller treatment, see electromagnetic radiation: Radio waves.)
How do you detect ultraviolet waves?
Ultraviolet can be detected by suitable photodiodes and photocathodes, which can be tailored to be sensitive to different parts of the UV spectrum. Sensitive UV photomultipliers are available. Spectrometers and radiometers are made for measurement of UV radiation. Silicon detectors are used across the spectrum.
What are examples of ultraviolet waves?
What Is Ultraviolet Light?
- UVA, or near UV (315–400 nm)
- UVB, or middle UV (280–315 nm)
- UVC, or far UV (180–280 nm)

Where do ultraviolet waves come from?
Ultraviolet radiation is produced by high-temperature surfaces, such as the Sun, in a continuous spectrum and by atomic excitation in a gaseous discharge tube as a discrete spectrum of wavelengths.
