MCQ
In stationary waves, antinodes are the points where there is
  • A
    Minimum displacement and minimum pressure change
  • B
    Minimum displacement and maximum pressure change
  • C
    Maximum displacement and maximum pressure change
  • ✓
    Maximum displacement and minimum pressure change
✓

Answer

Correct option: D.
Maximum displacement and minimum pressure change
d
Antinodes are the points on stationary wave with maximum displacement and maximum pressure change.Nodes are the point of zero displacement of particle and here pressure is also minimum.Antonodes are shown in the given figure.
