Question

what happens when the crests of a transverse wave move closer together? the amplitude is getting bigger. the wavelength is getting bigger. the wavelength is getting smaller. the amplitude is getting smaller.

Explanation:

In a transverse wave, the wavelength is the distance between two consecutive crests (or troughs). If the crests move closer together, the distance between them (wavelength) decreases. Amplitude is the maximum displacement from the rest position and is not related to the distance between crests.

Answer:

The wavelength is getting smaller.
