MCQ
Stationary waves
- ATransport energy
- BDoes not transport energy
- CHave nodes and antinodes
- ✓Both $(b)$ and $(c)$
✓
Answer
Correct option: D.
Both $(b)$ and $(c)$
d
Stationary waves do not transport energy. The energy gets cancelled out due to superposing of the two waves in opposite directions. These stationary waves have points which equals to zero at all time. These points are called nodes. Also there are points at which the amplitude gets to maximum or minimum at all time. These points are called antinodes.
