Waves are described and measured by five wave parameters: the period, the **frequency**, the **amplitude**, the wavelength, and the speed. The period of a wave is the time it takes to complete one cycle. The **frequency** is just the opposite; it's the number of wave cycles that are completed in one second.

People also ask, what is the relation between amplitude and frequency?

For any wave, the amplitude can be anything. There is a **simple** relationship between wavelength, frequency, and velocity. You can see this easily: a wave travels one wavelength L in one period P, so v = L/P. The period P is defined as the inverse of the frequency f, so P = 1/f.

How does the amplitude affect the frequency?

No real wave is perfectly linear. A very large **amplitude** can increase the speed of sound in a medium. If the medium is part a the source that employs resonance, then the **frequency** increases with the speed of the sound. The **frequency** of sound can **affect** the perceived loudness, where **amplitude** is held constant.
