EM spectrum

Here are the 7 from shortest to longest wavelength.

Frequency of Light The visible light frequency is 400 THz to 700 THz , approximately. A THz is a Terahertz, which is a unit of frequency equal to one trillion Hertz. The electromagnetic spectrum. The frequency increases as we move to the right.16 Eyl 2021
