Question

The string of a Sonometer is plucked so as to make it to vibrate in one segment The frequency produced in called.

• A. first Harmonic
• B. first Overtone
• C. second Harmonic
• D. second Overtone

Answer 1

The correct option is A first Harmonic

when a string is made to vibrato in one segment , then
length $l=\frac{\lambda }{2}$
$V=\frac{V}{4L}=V_o$
$(2n+1)=1\Rightarrow n=0$
$n=0$ corresponds to first harmonic
