If you set up the seventh harmonic on a string fixed at both ends, how many nodes and antinodes are set up in it
detailed solution
Correct option 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 = 7 + 1 = 8Talk to our academic expert!
