Question

formula of frequency length and tension of a stretched string

Answer 1

frequency =hertz
hope it help you

Answer 2

Factors on which frequency depends :

⇒ The frequency is directly proportional to the square root of tension.

⇒ The frequency is inversely proportional to the radius .

⇒ The frequency is inversely proportional to the density of the string.

The frequency can be increased by increasing tension , decreasing radius and density.

The frequency can be decreased by decreasing tension , increasing radius and density.

Formula :

$\mathsf{F=\frac{1}{2l}\frac{\sqrt{T}}{r^2d}}$
