In a stationary wave:
In a stationary wave:
- A. Strain is maximum at antinodes
- B. Strain is minimum at nodes
- C. Strain is maximum at nodes
- D. Amplitude is zero at all points
Step-by-step solution
In a stationary wave, strain (deformation) is proportional to the displacement gradient. At nodes, displacement is zero but the slope is maximum, so strain is maximum. At antinodes, displacement is maximum but slope is zero, so strain is minimum. Hence, option C is correct.
