Aug 14, · Learn the formula. The formula for frequency, when given wavelength and the velocity of the wave, is written as: f = V / λ In this formula, f represents frequency, V represents the velocity of the wave, and λ represents the wavelength of the wave.
Example: A certain sound wave traveling in the air has a wavelength of nm when 80%(34). The relative frequency of a data class is the percentage of data elements in that class. The relative frequency can be calculated using the formula, where is the absolute frequency and is the sum of all frequencies.
