Question

How does increasing frequency affect amplitude?

Answer 1

Amplitude and frequency:

1. Amplitude is the separation between the wave's resting position and its highest displacement.
2. Frequency is the number of waves that pass by a particular place each second.

The formula of amplitude:

$$\begin{gathered} \Rightarrow x=A\sin (\omega t+\varphi ) \\ \Rightarrow \frac{x}{A}=\sin (\omega t+\varphi ) \end{gathered}$$

Where, $x$= Displacement of the wave, in meters, $A$ = Amplitude of the wave, in meters, $\omega$ = Angular frequency of the wave, in radians, $t$ = time, in seconds, and $\varphi$ = phase shift, in radians.

Frequency effect on amplitude:

The wave's amplitude and frequency are related in such a way that they are inversely proportional to one another. The amplitude decreases with increasing frequency. The amplitude increases as the frequency decreases.
