There is formation of in all five nodes (including terminal nodes) in a string of 12 cm. Thus, wavelength of the waves formed is

Moderate

A

6.0 cm
B

4.8 cm
C

2.4 cm
D

1.2 cm

Solution

For n nodes in a string
$\begin{aligned} l = \frac{(n - 1) λ}{2} \\ 12 = \frac{(5 - 1) λ}{2} \\ λ = 6 .0 cm \end{aligned}$
