Velocity is almost always m/s while frequency is always in Hz (1/s). cadmium - Cadmium is the name for the element with atomic number 48 and is represented by the symbol Cd. These fundamental vibrations are referred to as "normal modes". 44 Votes) This example shows that knowing the frequency of an electromagnetic wave gives you the wavelength, since all electromagnetic waves travel at the speed of light so that c = v (lambda) where v is frequency and lambda is wavelength, and c is the speed of light. This list contains the 118 elements of chemistry. For the relationship to hold mathematically, if the speed of light is used in m/s, the wavelength must be in meters and the frequency in .
