- ✓Energy is minimum at nodes and maximum at antinodes
- CEnergy is maximum at nodes and minimum at antinodes
- DAlternating maximum and minimum energy producing at nodes and antinodes
✓
Answer
Correct option: B.
Energy is minimum at nodes and maximum at antinodes
b
In a stationary wave, node is the point where the amplitude always remains zero at all time and antinode is the point where amplitude will be either minimum or maximum at all time.
In a stationary wave, node is the point where the amplitude always remains zero at all time and antinode is the point where amplitude will be either minimum or maximum at all time.
When amplitude is at its extremum values the energy of the wave will also be maximum. Hence, it will have maximum energy at antinodes, When amplitude is zero, the energy will also be zero and is the least possible value for energy. Hence, it will have minimum energy at nodes.
