medium

Stationary waves are produced in $10\,m$ long stretched string. If the string Vibrates in $5$ segments and wave velocity $20\,m/s$ the frequency is ..... $Hz$

A

$10$

B

$5$

C

$4$

D

$2$

Solution

${n_p}\, = \,\frac{{pV}}{{2l}}\, = \,\frac{{5 \times 20}}{{2 \times 10}}\,\, = 5{\mkern 1mu} {\mkern 1mu} Hz$
