Question

A stretched string of length $l,$ fixed at both ends can sustain stationary waves of wavelength $\lambda,$ given by

• A. $\lambda = \frac{n^{2}}{2l}$
• B. $\lambda = \frac{l^{2}}{2n}$
• C. $\lambda = \frac{2l}{n}$
• D. $\lambda = 2l\mspace{6mu} n$

Answer 1

Answer: (C)

$\lambda = \frac{2l}{n}$

Answer 2

$\lambda = \frac{2l}{p}$ (p = Number of loops)
