If you set up the seventh harmonic on a string fixed at both ends, how many
nodes and antinodes are set up in it
[AMU 2000]
8, 7
String will vibrate in 7 loops so it will have 8 nodes 7 antinodes.
Number of harmonics = Number of loops
Number of antinodes = 7
Hence number of nodes = Number of antinodes + 1
=7+1=8
