Question

A student is labeling one wavelength on a longitudinal wave. She marks the beginning of the wavelength at a compression. Which point on the wave should the student mark as the end of the wavelength?
a. the next compression
b. two compressions later
c. the next rarefaction
d. two rest positions later

Answer 1

Answer:

The correct answer would be A. the next compression.

Explanation:

This is because each compression marks the smallest amount of spacing between two crests. The distance between two crests is called a wavelength.
