    Frequency, also called wave frequency, is a measurement of the total number of vibrations or oscillations made within a certain amount of time. There are a few different ways to calculate frequency based on the information you have available to you. Keep reading to learn some of the most common and useful versions.

    The formula for frequency, when given wavelength and the velocity of the wave, is written as:

    f = V / λ

    represents the velocity of the wave, and

    represents the wavelength of the wave.

    Example: A certain sound wave traveling in the air has a wavelength of 322 nm when the velocity of sound is 320 m/s. What is the frequency of this sound wave?

    Convert the wavelength into meters, if necessary.

    The formula for the frequency of a wave in a vacuum is almost identical to that of a wave not in a vacuum. Since there are no outside influences on the velocity of the wave, though, you would use the mathematical constant for the speed of light, which electromagnetic waves would travel at under these conditions. As such, the formula is written as:

    f = C / λ

    represents the velocity or speed of light, and

    represents the wavelength of the wave.

    Example: A particular wave of electromagnetic radiation has a wavelength of 573 nm when passing through a vacuum. What is the frequency of this electromagnetic wave?

    Convert the wavelength into meters, if necessary.

    Frequency and the time taken to finish a single wave oscillation are inversely proportional. As such, the formula for calculating frequency when given the time taken to complete a wave cycle is written as:

    f = 1 / T

    represents the time period or amount of time required to complete a single wave oscillation.

    Example A: The time for a certain wave to complete a single oscillation is 0.32 seconds. What is the frequency of this wave?

    Example B: In 0.57 seconds, a certain wave can complete 15 oscillations. What is the frequency of this wave?

    Divide the number of oscillations by the time period.

    When told the angular frequency of a wave but not the standard frequency of that same wave, the formula to calculate the standard frequency is written as:

    f = ω / (2π)

    represents the frequency of the wave and

    represents the angular frequency. As with any mathematical problem,

    stands for pi, a mathematical constant.

    Example: A particular wave rotates with an angular frequency of 7.17 radians per second. What is the frequency of that wave?
