Question

where can wavelengths be measured in a transverse wave? select all correct options. from crest to crest. from crest to trough. from trough to trough.

Explanation:

The wavelength of a transverse wave is the distance between two consecutive identical points on the wave, such as two consecutive crests or two consecutive troughs. The distance from crest to trough is half a wavelength (since from crest to trough to the next crest is a full wavelength, so crest to trough is $\frac{1}{2}$ wavelength). So the correct options are the ones where we measure between consecutive crests or consecutive troughs.

Answer:

A. From crest to crest
C. From trough to trough
