Hint: The scope of all types of EM radiation is the electromagnetic (EM) spectrum. Microwaves, infrared light, ultraviolet light, X-rays and gamma-rays are the other types of EM radiation that make up the electromagnetic spectrum. You know more than you might imagine about the electromagnetic spectrum.

Complete step-by-step solution
1.Frequency
The electromagnetic spectrum (EMS) is the general name given to the electromagnetic radiation range that is known. Wavelengths rise from about $10^{-18} \mathrm{~m}$ to $100 \mathrm{~km},$ and this refers to frequencies decreasing from $3 \times 10^{26} \mathrm{Hz}$ to $3 \times 10^{3}$ Hz. So we have radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays, from the lowest to the highest frequency.
2. Wavelength
Electromagnetic waves are categorized by frequency ‘f’ or, equivalently, by wavelength $\lambda=\mathrm{c} / \mathrm{f}$. Visible light has ranged from 400 nm to 700 nm in wavelength. Ultraviolet light, X-rays, and gamma rays include electromagnetic waves with shorter wavelengths and greater frequencies.
3. Source
All radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays are included in the whole electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength). Radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays, are examples of EM radiation.
4. Detection
Use a conducting rod to detect the electric fields. The fields cause charges on the rod to accelerate back and forth (usual electrons), creating a potential difference that oscillates at the EM wave frequency and with an amplitude proportional to the wave amplitude. Spectroscopy is able to detect a much wider region of the EM spectrum than the visible wavelength range of 400 nm to 700 nm in a vacuum.
5. Application and Uses
They are used to transmit radio waves of short or long or FM wavelengths. They are used for the transmission of television, telephone, or wireless signals and energy. They are responsible for microwave-like energy transmission, visible light, infrared radiation, ultraviolet light, gamma rays, as well as X-rays. While all electromagnetic waves travel at the speed of light in a vacuum, they do so at a broad variety of photon frequencies, wavelengths, and energies.

Note: In terms of energy, wavelength, or frequency, electromagnetic radiation can be expressed. Frequency is measured, or Hertz, in cycles per second. In metres, the wavelength is measured. In electron volts, energy is measured. Each of these three quantities are related to each other in a precise mathematical manner to describe EM radiation.
