Question

Standing waves are produced on a stretched string of length L with fixed ends. When there is a node at a distance U/3 from one end, then $N=$ velocity of waves in the string]

• A. minimum and next higher number of nodes excluding the ends are $2,5$ respectively
• B. minimum and next higher number of nodes excluding the ends are $2,4$ respectively
• C. frequency produced may be V/(3L)
• D. frequency produced may be 3$V/\left(2L\right)$

Answer 1

Answer: (A), (D)

The correct options are
A minimum and next higher number of nodes excluding the ends are $2,5$ respectively
D frequency produced may be 3$V/\left(2L\right)$
