Question
State the laws of vibrating strings and explain how they can be verified using a sonometer.
✓

Answer

The fundamental is the first harmonic. Therefore, the ratio of the fundamental frequency $(n)$ to the second harmonic $(n_1)$ is $1 : 2$.
Here, $L=3 \frac{\lambda}{2}$
$\therefore$ Wavelength, $\lambda=\frac{2 L}{3}=\frac{2 \times 30}{3}=20 cm$.
