Question

A $12m$ long vibrating string has the speed of wave $48m/s$ to what frequency it will resonate?

• A. $2cps$
• B. $4cps$
• C. $6cps$
• D. All of these

Answer 1

The correct option is D All of these

Given, $S=48m/s,l=12m$

So, Equation of the fundamental frequency:

$v\frac{v}{2l}=\frac{48}{2\times 12}=2cps$

The string will resonate at fundamental frequency as well as first overtone second overtone and so on.
