If you set up the seventh harmonic on a string fixed at both ends, how many nodes and antinodes are set up in it

A

8, 7

B

7, 7

C

8, 9

D

9, 8

Text Solution

Verified by Experts

The correct Answer is:
A
`7^(th)` harmonic implies `n=7`
For both ends fixed, number of antinodes, n = 7
`therefore` nodes = `(n+1)=8`.
