In a standing wave, node is a point of
- A. maximum strain
- B. maximum pressure
- C. maximum density
- D. All of these
Step-by-step solution
In a standing wave, nodes are points of zero displacement. At these points, the strain (deformation) is maximum due to maximum displacement gradient. Also in longitudinal waves, nodes correspond to maximum pressure and density variations because the medium is alternately compressed and rarefied most at these points. Therefore, all given options (maximum strain, maximum pressure, maximum density) are correct.
