Question

if you increase the amplitude, what would it affect? level up! + 100 volume wavelength frequency pitch

Explanation:

In the context of sound waves (a topic in Physics, a subfield of Natural Science), amplitude is related to the energy of the wave. An increase in amplitude affects the loudness or volume of the sound. Wavelength is related to the distance between wave crests, frequency to the number of waves per unit time, and pitch is related to frequency. So the correct option is the one with "volume".

Answer:

The option with "volume" (the red-colored option labeled "volume")
