Question
Physics Question on Waves
Identify the correct statement about a stationary wave
A
Stationary wave is formed by superposition of two waves of different frequencies
B
The energy of oscillation is minimum at the antinode
C
Amplitude at the antinode is the same as that at the node
D
The pressure change is least at the antinode
Answer
The pressure change is least at the antinode
Explanation
Solution
(a) Stationary wave is formed by superposition of two waves of same frequencies
(b) The energy of oscillation is maximum at the antinode
(c) Amplitude at the antinode is different from as that at the node. It is maximum at the antinode and zero at the node
(d) The pressure change is least at the antinode
