Question

A 12 metre long vibrating string has the speed of wave 48 M per second to what frequency it will resonate

Answer 1

disatance = speed x time
48/12 = 4

Answer 2

Answer:

Frequency of the wave, f = 4 Hz

Explanation:

It is given that,

Length of the vibrating string, l = 12 m

Speed of a wave, v = 48 m/s

We know that, the relation between the frequency and the speed of the wave is :

$v=f\times \lambda$

$f=\dfrac{v}{\lambda}$

$f=\dfrac{48\ m/s}{12\ m}$

$f=4\ Hz$

It will resonates at the frequency of 4 Hz. Hence, this is the required solution.
