Work Step by Step

Electromagnetic radiation (EMR) is a type of energy that travels through space as a wave. The four types of EMR mentioned in the question are ultraviolet (UV), microwaves, gamma rays, and visible light. Wavelength: The wavelength of a wave is the distance between two consecutive peaks or troughs of the wave. In EMR, the wavelength is typically measured in nanometers (nm) or micrometers (µm) for visible light and in Angstroms (Å) for UV and X-rays. Frequency: The frequency of a wave is the number of oscillations or cycles that the wave completes in one second. The unit of frequency is hertz (Hz). Photon energy: The energy of a photon is the amount of energy carried by a single photon of EMR. Photon energy is related to both wavelength and frequency; shorter wavelengths and higher frequencies correspond to higher photon energies. The unit of energy is electronvolt (eV). Speed of travel: The speed of travel of EMR is the speed at which the wave travels through a vacuum, which is the speed of light (c = 3 x 10^8 m/s). The four types of electromagnetic radiation in order of increasing wavelength are: Gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves and radio waves. The four types of electromagnetic radiation in order of increasing frequency are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, Gamma rays The four types of electromagnetic radiation in order of increasing photon energy are: Gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, radio waves The four types of electromagnetic radiation in order of increasing speed of travel are: All the types of electromagnetic radiation travels with the same speed of 3*10^8 m/s. It's important to note that these values are approximate and may vary depending on the specific wavelength, frequency, photon energy, and speed of travel for a given type of electromagnetic radiation.
