The diagram below represents a wave traveling to the right along an elastic medium.

Question

What is the wavelength of the wave?
A.
0.25 m

B.
0.50 m

C.
0.75 m

D.
1.50 m

Answer 1

Without the diagram, it is difficult to determine the wavelength of the wave accurately. The wavelength is the distance between two consecutive points of similar position on the wave, such as the crests or the troughs. To determine the wavelength, it is necessary to measure the distance between two consecutive crests or troughs on the diagram.
