In stationary waves, nodes are the points where there is:
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
Step-by-step solution
In stationary waves, nodes are points of zero displacement, so displacement is minimum. However, the pressure variation is maximum at nodes because the particles are alternately compressed and rarefied, leading to maximum pressure change.
