Physics - Sound Wave Question with Solution | TestHub

Human ear can hear frequencies upto $20,000\mathrm{Hz}$. So for closed pipe, overtone, $\mathrm{v}=\frac{nv}{4L}=n\times$ fundamental frequency $$\therefore 20,000=n\times 1500\Rightarrow n\approx 13\text{. }$$ Maximum possible harmonics obtained $$=1,3,5,7,9,11,13\dots \dots \dots \dots$$ Therefore one can hear maximum upto $13^{\text{th }}$ harmonics. Overtone $=7-1=6$
