Question
In a transverse wave ______ and _______ are generated.
- Crest, hills
- Troughs, valleys
- Compression, rarefaction
- Crest, trough
The correct answer is: Crest, trough
In a transverse wave when it propagates through a medium crests and troughs or hills and valleys are generated.
Hence, (D) Crest, trough is the right answer.
