Question

A string vibrates in 5 segments to a frequency of 480 Hz. The frequency that will cause it to vibrate in 2 segments will be:

• A. 96 Hz
• B. 192 Hz
• C. 1200 Hz
• D. 2400 Hz

Answer 1

The correct option is B 192 Hz

$f=480Hz$
$f=\frac{n}{2l}\sqrt{\frac{T}{n}}$
$\Rightarrow =\frac{f_1}{n_1}=\frac{f_2}{n_2}\Rightarrow \frac{480}{5}=\frac{f_2}{2}$
$f_2=192Hz$
