Question

which wave would produce the highest pitch sound? 2 because it has the largest amplitude 1 because it has the longest wavelength 3 because it has the greatest frequency they all will produce the same pitch

Explanation:

Step1: Recall sound - pitch relationship

The pitch of a sound is determined by its frequency. Higher - frequency waves produce higher - pitch sounds.

Step2: Analyze wave frequencies

Wave 3 has the smallest wavelength among the given waves. Since frequency $f=\frac{v}{\lambda}$ (where $v$ is the wave speed, which is constant in a given medium), a smaller wavelength corresponds to a higher frequency.

Answer:

3 because it has the greatest frequency
