Question

A string fixed at both the ends is vibrating in two segments. The wavelength of the corresponding time is

• A. $l/4$
• B. $l/2$
• C. $l$
• D. $2l$

Answer 1

Answer: (C)

Distance between two consecutive nodes is $\frac{\lambda }{2}$.
Therefore, $l=2\times \frac{\lambda }{2}$
or $\lambda =l$
