WebOptical Frequency. The optical frequency (for example of a quasi-monochromatic laser beam) is the oscillation frequency of the corresponding electromagnetic wave. For visible light, optical frequencies are roughly between 400 THz (terahertz = 10 12 Hz = 1 trillion hertz) and 700 THz, corresponding to vacuum wavelengths between 700 nm and 400 nm.
