Question

Choose the correct statement from the following options.

• A. The distance between any two consecutive antinodes or nodes is $\frac{\lambda }{4}.$
• B. The distance between a node and adjoining antinode is $\frac{\lambda }{4}.$
• C. In the open end, there is a node
• D. In the closed end, there is an antinode.

Answer 1

Answer: (B)

The distance between any two consecutive antinodes or nodes is $\frac{\lambda }{2}$ .
Hence, option $\left(A\right)$ is an incorrect statement.
The distance between a node and adjoining antinode is $\frac{\lambda }{4}$ .
Hence, option $(B)$ is a correct statement.
In the open end is an antinode.
Hence, option $\left(C\right)$ is an incorrect statement.
In the closed end is a node.
Hence, option $(D)$ is an incorrect statement.
