EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays .
Read moreDo electromagnetic waves have different frequency?
Electromagnetic waves vary in wavelength and frequency . Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy. The speed of a wave is a product of its wavelength and frequency.
Read moreHow do you find the frequency of an electromagnetic wave?
Electromagnetic waves are transverse waves. The wave number is k = 2π/λ, where λ is the wavelength of the wave. The frequency f of the wave is f = ω/2π , ω is the angular frequency.
Read moreWhat are the uses of microwaves?
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 …
Read moreWhat are the 7 types of electromagnetic waves in order?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays .
Read moreWhat is the electromagnetic spectrum simple definition?
The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation . Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.
Read moreHow do you explain the electromagnetic spectrum to a child?
The electromagnetic spectrum is set up based on this idea. The order from longest wavelength (lowest energy) to shortest wavelength (highest energy) is: radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays and gamma rays.
