Question

Graph shows three waves that are separately sent along a string that is stretched under a certain tension along x-axis. If ${\omega }_1,{\omega }_{2}and{\omega }_3$ are their angular frequencies, respectively, then:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

$If{f}_1=fthen,f_2=\frac{f}{2},f_3=f$
$\therefore {\omega }_1=2\pi f\Rightarrow {\omega }_3=2\pi fand{\omega }_2=\pi f$
