Question

In stationary waves, nodes are the points where there is:

• A. maximum displacement and minimum pressure change
• B. minimum displacement and maximum pressure change
• C. minimum displacement and minimum pressure change
• D. maximum displacement and maximum pressure change

Answer 1

Answer: (B)

minimum displacement and maximum pressure change

In physics, a standing wave or stationary wave is a wave that oscillates in time. But whose peak amplitude profile does not move in the space. The peak amplitude of the wave oscillations at any point is constant. Its oscillations at different points throughout the wave are in phase.

At the nodes in stationary waves, the pressure change is maximum while the displacement will be minimum. Therefore, option B is the correct statement.

Option B is correct.
