Question
A second harmonic has to be generated in a string of length $l$ stretched between two rigid supports. The point where the string has to be plucked and touched are
✓
Answer
(a) Second harmonic means $2$ loops in a total length
Hence plucking distance from one end $ = \frac{l}{{2p}} = \frac{l}{{2 \times 2}} = \frac{l}{4}.$
Hence plucking distance from one end $ = \frac{l}{{2p}} = \frac{l}{{2 \times 2}} = \frac{l}{4}.$
