For the relationship to hold mathematically if the speed of light is used in ms the wavelength must be in meters and the frequency in Hertz. In the electromagnetic spectrum there are many different types of waves with varying frequencies and wavelengths. That number also known as the frequency will be larger for a short-wavelength wave than for a long-wavelength wave.
The relation ship between velocity frequency and wave length of a wave is given by the formula v l Here velocity v 3434 ms -1.
They are all related by one important equation. Thus the frequency of the first wave is greater than that of the second wave. Thus the frequency of the first waves is greater than that of the second waves. As the wavelength of a wave increases its frequency decreases.
