If you set up the seventh harmonic on a string fixed at both ends, how many nodes and antinodes are set up in it
Text Solution
Verified by ExpertsThe correct answer is:
A
String will vibrate in 7 loops so it will have 8 nodes 7 antinodes.
Number of harmonics = Number of loops = Number of antinodes ⇒ ⇒ Number of antinodes = 7
Hence number of nodes = Number of antinodes + 1
