The formula for beat frequency is f_beat = |f_1 - f_2|, where f_beat is the beat frequency and f_1, f_2 are the frequencies of the two interfering waves.
The unit of measurement for frequency of wavelengths per second is Hertz (Hz).
The unit of measurement for electromagnetic wave frequency is hertz (Hz), which represents one cycle per second.
It may be called the pitch, the frequency, or the wavelength.A low-pitched sound has a low frequency and a long wavelength.A high-pitched sound has a high frequency and a short wavelength.
Wavelength is the distance between two consecutive points on a wave that are in phase (e.g., peak to peak), while frequency is the number of wave cycles passing a fixed point in one second. In other words, wavelength is a spatial measurement, while frequency is a temporal measurement.
The CRT display becomes an electronic graph of two instantaneous voltages. The display may be a direct comparision of two voltages such as during phase measurement, or frequency measurement with Lissajous waveforms.
The frequency distribution usually refers to empirical measurement and there is no formula for finding it. You simply count the number of times an observation falls within a given range.
If you must use an oscilloscope, then using Lissajous Figures will give you exact multiples of a given frequency. Naturally, you must have a known reference frequency at hand.These days a Frequency Counter will give adequate resolution.
Jules Antoine Lissajous died in 1880.

There is no formula for measurement.
