Frequency is defined as how many waves pass by a point in one second.

Explanation:
Frequency is the rate at which waves pass a fixed point each second. When you count how many wave crests cross a point in one second, you’re measuring how often those waves occur, which is frequency. It’s measured in hertz, or cycles per second. This is different from amplitude, which describes how tall or strong the wave is; wavelength, which is the distance between successive crests, and speed, which is how fast the wave travels. The speed of a wave is related to frequency and wavelength by the equation v = f λ, but frequency itself is specifically that count per second.
