What frequency does light vibrate at?

Gigahertz (GHz) is a frequency unit that measures the number of cycles per second . Hertz (Hz) refers to the number of cycles per second with periodic 1-second intervals. One megahertz (MHz) equals 1,000,000 Hz. One gigahertz is equal to 1,000 megahertz (MHz) or 1,000,000,000 Hz.

Shorter waves vibrate at higher frequencies and have higher energies. Red light has a frequency around 430 terahertz, while blue’s frequency is closer to 750 terahertz . Red photons of light carry about 1.8 electron volts (eV) of energy, while each blue photon transmits about 3.1 eV.

Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz. Visible light makes up just a small part of the full electromagnetic spectrum. … The EM spectrum.
