Question

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
• D. Maximum displacement and minimum pressure change

Answer 1

Antinodes points

1. Antinodes are the points on a stationary wave with maximum displacement and maximum pressure change.
2. Nodes are the point of zero displacements of particles and here pressure is also minimum. Antinodes are shown in the given figure.

The correct option is D
