A stretched string is vibrating in the second overtone, then the number of nodes and antinodes between the ends of the string are respectively [KCET 2015]
3 and 4
4 and 3
2 and 3
3 and 2
Solution
A stretched string is vibrating such that
2nd overtone = 3rd harmonic
[Diagram shows a standing wave with 3 loops, indicating antinodes $A$ at the peaks and nodes $N$ at fixed ends and nodal points]
There are 2 nodes and 3 antinodes present.
