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.

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.

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.
