Nodes and antinodes are formed in the
- A.
Transverse wave
- B.
Stationary wave
- C.
Progressive wave
- D.
Longitudinal wave
Correct Answer
D. Longitudinal waveExplanation
Nodes and antinodes are formed in a longitudinal wave. In a longitudinal wave, the particles of the medium vibrate parallel to the direction of wave propagation. Nodes are the points in the wave where the particles of the medium do not vibrate, while antinodes are the points where the particles vibrate with maximum amplitude. This is in contrast to transverse waves, where the particles vibrate perpendicular to the direction of wave propagation. Stationary waves are formed when two waves of the same frequency and amplitude traveling in opposite directions superpose, resulting in nodes and antinodes. Progressive waves are waves that transfer energy from one point to another.Rate this question:
