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
Answer
8, 7
Explanation
Solution
String will vibrate in 7 loops so it will have 8 nodes 7 antinodes. Number of harmonics = Number of loops = Number of antinodes
ā Number of antinodes = 7
Hence number of nodes = Number of antinodes + 1
=7+1=8
