In a stationary wave
A
pressure change is maximum at nodes
B
pressure change is maximum at antinodes
C
pressure change is minimum at nodes
D
amplitude is zero at all points
Answer
pressure change is maximum at nodes
Explanation
Solution
A node is formed when two particles out of phase interfere with each others. At those point two opposing forces act simultaneously, thereby increasing the strain and the pressure.
