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) \[2l\]

Correct Answer: C

Solution :

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