MCQ
A stretched string fixed at both ends has $m$ nodes, then the length of the string will be
  • $(m-1) \frac{\lambda}{2}$
  • B
    $\frac{(m+1) \lambda}{2}$
  • C
    $\frac{m \lambda}{2}$
  • D
    $(m-2) \frac{\lambda}{2}$

Answer

Correct option: A.
$(m-1) \frac{\lambda}{2}$
(a)Image
In case of a stretched string fixed at both ends has $m$ nodes, then the length of the string will be $L=(m-1) \frac{\lambda}{2}$, where $\lambda$ is the wavelength.
