Question

State factors on which frequency of fundamental note of a vibrating string depends.

Answer 1

1. The frequency of vibration of the fundamental note depends on various factors.
2. Fundamental frequency $=\frac{1}{2l}\sqrt{\frac{T}{\mu }}$

Where $\mu =$mass per unit length

$T$$=$ Tension in the string

$l$$=$ Length of string

3. From the above formula we can say the frequency of fundamental nodes depends on the length of string, mass per unit length, and tension in the string.
