Q. A stretched string of length 𝒍 fixes at both ends can sustain stationary waves of wavelength λ, given by
A) $\lambda$ =2𝒍n
B) $\lambda = \frac{\iota^{2}}{n}$
C) $\lambda = \frac{\iota^{2}}{2n}$
D) $\lambda = \frac{n^{2}}{2\iota}$
Explanation
(b) As we know that
$\frac{n\lambda}{2} = I\ \ or\ \lambda = \frac{2l}{n}$
