Answer:
B D
Explanation:
Waves have moving crests (or peaks) and troughs. A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to. A crest is a point on the wave where the displacement of the medium is at a maximum. A point on the wave is a trough if the displacement of the medium at that point is at a minimum.
The wavelength of a sound wave is the distance between successive crests and troughs. Therefore, half the wavelength is the distance covered by one crest or one trough. In this case, the points marked BD is half the wavelength.
