What is the distance between one point on a wave and the nearest point like it (such as compression to compression or rarefaction to rarefaction)?

What is the distance between one point on a wave and the nearest point like it (such as compression to compression or rarefaction to rarefaction)?

• A. Amplitude
• B. Wavelength
• C. Frequency
• D. Period

Answer: (B)

The main idea is the wavelength, which is the spatial distance over which a wave pattern repeats. For both transverse waves and longitudinal waves, you can measure this distance between identical points in the pattern: crest to crest or trough to trough in a transverse wave, and compression to compression or rarefaction to rarefaction in a longitudinal wave. This distance is about how far the wave travels before the pattern repeats in space, and it is measured in meters. Amplitude describes how far the medium moves from rest, frequency tells how many cycles occur each second, and period is the time for one full cycle. So the distance between identical points in successive repeats is the wavelength.
