Question
The diagram below shows two longitudinal waves, wave X and wave Y, at one instant of their motion. Each oval represents a particle acted on by the energy of the wave as it moves from left to right. The number of ovals carrying wave X is equal to the number of ovals carrying wave Y.
Comparing the two, it appears that wave X has a greater _______ than wave Y.
A.
frequency
B.
period
C.
wavelength
D.
amplitude

C. wavelength
Explanation: From the snapshot you can see the spacing between successive compressions/rarefactions for wave X is larger than for wave Y, so X has a longer wavelength. You cannot tell frequency or period from a single instant, and amplitude (particle displacement) is not shown as larger for X.
