Physics - Sound Wave Question with Solution | TestHub

At $\mathrm{t}=0$ a sound source S and observers ${\mathrm{O}}_1$ & ${\mathrm{O}}_2$ are placed as shown. S is moving with speed ${\mathrm{V}}_1$ and ${\mathrm{O}}_1$ and ${\mathrm{O}}_2$ are moving with speed ${\mathrm{V}}_0$. At any later instant, let ${\mathrm{f}}_1$ and ${\mathrm{f}}_2$ represent apparent frequencies of sound observed by $O_1$ and $O_2$ respectively. The ratio $f_1/f_2$ is (Note : $V_1$ and $V_0$ are less than speed of sound in this medium).
