The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves⦠The electromagnetic field is generated by the acceleration of the electrons of the cathode. Whereas radio waves can be up to a mile in length, microwaves measure from a few centimetres up to a foot. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*10 14 Hz. Radio wave photons have the lowest energy in the electromagnetic spectrum. Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Like all other electromagnetic waves, radio waves ⦠7 types of electromagnetic waves. Ordering them from the highest frequency to the lowest frequency, they are: - Gamma rays - X-rays - Ultraviolet - Visible light - Infrared radiation - Microwaves - Radio waves Radio waves. Explanation: The electromagnetic spectrum includes all different types of waves, which are usually classified depending on their frequency. These heat waves are emitted by thermal bodies, some types of lasers and diodes that emit light. Which has the highest frequency, lowest frequency, highest energy, and lowest energy? Arrange the following types of electromagnetic radiation in order of increasing energy A) ultraviolet light B) microwaves C) radio waves ⦠The order of energy from least to greatest is: microwaves, infrared, red, ultraviolet, and gamma waves. ... Gamma waves are the highest-frequency EM waves⦠Infrared rays . Electromagnetic Waves in Electromagnetic Spectrum. Its behavior is also dependent on the frequency of the wave. The regions of the electromagnetic spectrum are explained below in order of increasing wavelength and decreasing frequency. Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Written on: July 14, 2020 ... Microwaves are the second-lowest frequency waves in the EM spectrum. Visible light has a wavelength range from ~400 nm to ~700 nm. All types of electromagnetic radiation are transverse waves and they all travel at the same speed in a vacuum. The entire range (electromagnetic spectrum) is given by radio waves, microwaves, infrared radiation, visible light, ultra-violet radiation, X-rays, gamma rays and cosmic rays in the increasing order of frequency ⦠Although they often overlap with radio waves and microwaves, their range is between 0.7 ⦠All of the waves are Transverse waves and travel like a wave you see on the sea's horizon. Red light has a wavelength of ~700 nm, and a frequency ⦠The energy of an electromagnetic wave is directly proportional to its frequency. This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave. Written by: Luc Braybury. They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. You can ⦠UV IR X-rays visible radio γ -rays microwave 7. The Electromagnetic spectrum is made up of 7 colours and 7 types of radiation. This means that the greater the frequency, the greater the energy. It is about a femtoelectronvolt of energy.
