Question

_____ waves consist of crests and troughs.

Answer 1

1. Transverse waves are those waves in which the medium particles vibrate perpendicularly to the direction of wave propagation.
2. Transverse waves travel in the form of crests and troughs.
3. A crest is the highest point of displacement while a trough is the lowest point of displacement of the medium particles.

Hence, transverse waves consist of crests and troughs.
