Question

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

Answer 1

String will vibrate in 7 loops so it will have 8 nodes 7 antinodes. Number of harmonics = Number of loops = Number of antinodes Þ Number of antinodes = 7 Hence number of nodes = Number of antinodes + 1 =7+1=8
