The number of cycles per second is called what, indicated by the symbol F?

Explanation:
Frequency measures how often a repeating event occurs in a unit of time, specifically how many cycles pass a point each second. The symbol F is commonly used for this rate, and the unit is hertz (Hz), meaning cycles per second. A handy link is f = 1/T, where T is the time for one cycle (the period). Frequency also connects to speed and wavelength through v = fλ: at a given speed, higher frequency means shorter wavelength. The other terms describe different wave properties: wavelength is the spatial length of one cycle, amplitude is the height or strength of the wave, and phase is the position within the cycle at a given moment.
