Typical Vibrational Frequencies of Inorganic Species 1. Typically, frequency is measured in units of cycles per second or waves per second. Looking for the abbreviation of Frequency? There are two equations concerning light that are usually taught in high school. Share 1 Repair minor damage (ex. The product of a wave’s wavelength ( λ) and its frequency ( ν ), λν, is the speed of the wave. It will be given in 1/min, as revolutions per minute, or as in rpm. Other times, they may be completely unrelated to the name of the physical quantities, like c, which stands for the speed of light. The fact that cm is asked for in the problem allows us to use the cm/s value for the speed of light: I could also have used (1 Å / 10-8 cm) for the conversion. The usual symbols for frequency are the Latin letter f or the Greek letter ν (nu). There is an important point to make about the unit on Hz. See reference 2 for a description of the vibrations associated with each frequency. The period or duration of time of a cycle of a wave is the reciprocal (1 divided by) of frequency. Notice how the frequencies stay within more-or-less the middle area of 1014, ranging from 4.29 to 7.50, but always being 1014. Comment: be aware that the range of 4000 to 7000 Å is taken to be the range of visible light.
