The answer is electromagnetic spectrum
The answer is electromagnetic spectrum
The range of electromagnetic waves when placed in order of increasing frequency is called the electromagnetic spectrum. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

The answer is electromagnetic spectrum
The electromagnetic spectrum is the name for the range of electromagnetic waves when they are placed in order of increasing frequency. The electromagnetic spectrum is made up of radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.
The frequency range for electromagnetic waves is from about 3 Hz (hertz) to 300 EHz (exahertz).
The lowest frequency is effectively zero and this would be in the extremely low frequency (ELF) band in the sub-radio range of the electromagnetic spectrum.
Electromagnetic Frequency (EMF) & Radio Frequency (RF)
Electromagnetic Frequency (EMF) & Radio Frequency (RF)
Visible light has the highest frequency in the electromagnetic spectrum. It falls between ultraviolet and infrared light, with a frequency range of approximately 430 to 750 terahertz (THz).
The entire range of electromagnetic frequencies is called the electromagnetic spectrum. This spectrum includes all forms of electromagnetic radiation, from radio waves to gamma rays.
If an electromagnetic wave has a frequency of 100 Hz, then its wavelengthin vacuum is almost 1,900 miles, and we would call it a radio wave in the ELF(extremely low frequency) range.
