Question

If a stereo has a dial that changes the volume of the sounds the stereo makes, what is the dial doing?

Answer 1

changing the amplitude of the sound waves

Step-by-step explanation:

The amplitude of a sound wave is a measure of how loud the sound produced by the wave is. Sound waves with higher amplitudes produce louder sounds, while sound waves with lower amplitudes produce quieter sounds. So changing the volume of a sound means that the amplitude of the sound waves changes.
