Question

multiple choice question
reflected waves that interfere with incoming waves of the same frequency produce ______ waves.
o sitting
o standing
o noise
o beating

Explanation:

When reflected waves interfere with incoming waves of the same frequency, standing waves are formed. Standing waves have points of zero displacement (nodes) and points of maximum displacement (antinodes) that do not move. Sitting is not a type of wave. Noise is random, irregular sound. Beating occurs when two waves of slightly different frequencies interfere.

Answer:

B. standing
