Question

which wave has the longest wavelength? wave x wave z wave y 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.

Explanation:

Step1: Understand wavelength definition

Wavelength is the distance between two repeating points on a wave.

Step2: Compare wave lengths

Looking at the waves X, Y, and Z. Wave X has the largest distance between its repeating points (as per the visual representation in the diagram).

Answer:

Wave X
