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. Webif binding is partly ionic, then optic mode has a dipole moment interacting with radiation. Optic mode can be excited by light. For p atoms in primitive cell, there are 3p branches 3 …
