The electromagnetic spectrum encompasses a wide range of frequencies, from extremely low frequencies to extremely high frequencies. The highest and lowest frequencies in the electromagnetic spectrum are as follows:
The highest frequencies in the electromagnetic spectrum are associated with gamma rays. Gamma rays have the shortest wavelengths and highest frequencies among all electromagnetic waves. They have frequencies greater than 10^19 hertz (Hz) and can extend up to the range of a few exahertz (10^18 Hz).
On the other end of the spectrum, the lowest frequencies are associated with radio waves. Radio waves have the longest wavelengths and lowest frequencies. The frequency range of radio waves starts from a few hertz (Hz) and can extend to several terahertz (10^12 Hz) for certain specialized applications.
Between these extremes, the electromagnetic spectrum includes other types of waves, such as microwaves, infrared waves, visible light, ultraviolet waves, and X-rays, each with its own characteristic range of frequencies and wavelengths.
It's important to note that the division of the electromagnetic spectrum into specific ranges can vary depending on different sources and applications. The frequencies provided above serve as general reference points for the highest and lowest frequencies in the spectrum.
