A string of length $l$ fixed at both the ends is vibrating in two segments. The wavelength of the corresponding wave is
$\frac{l}{4}$
$\frac{l}{2}$
$l$
$2l$
Solution
The following figure shows string vibrating in two segments.
[Diagram shows a string of length $l = \lambda$ fixed at both ends vibrating in two loops with nodes at $x=0, l/2, l$ and antinodes at $x=l/4, 3l/4$]
The wavelength of the corresponding wave is $l$.
