Question

the wavelength is the distance between two repeating points on a wave. often the crests, or highest points of waves, are used to measure wavelength. a sound wave with a shorter wavelength has a higher pitch. a sound wave with a longer wavelength has a lower pitch. choose the correct answer. which sound wave has the highest pitch? wave z wave y wave x

Explanation:

The pitch of a sound wave is related to its frequency. A higher - frequency sound wave has a higher pitch. Frequency is inversely related to wavelength ($f=\frac{v}{\lambda}$, where $v$ is the speed of sound, assumed constant in a given medium). A shorter wavelength means a higher frequency. Looking at the waves, Wave Z has the shortest wavelength among the three (as it has the most oscillations in a given space).

Answer:

Wave Z
