A) \[\lambda =\frac{{{n}^{2}}}{2l}\]
B) \[\lambda =\frac{{{l}^{2}}}{2n}\]
C) \[\lambda =\frac{2l}{n}\]
D) \[\lambda =2\ln \] (Here, n is a integer)
Correct Answer: C
Solution :
If number of loops in string is n, then, \[l=\frac{n\lambda }{2}\]\[\Rightarrow \]\[\lambda =\frac{2l}{n}\]You need to login to perform this action.
