Physics - Sound Wave Question with Solution | TestHub

A source of sound$\mathrm{S}$emitting waves of frequency$\text{100 Hz}$and an observer$\text{O}$are located at some distance from each other. The source is moving with a speed of$19.4\mathrm{ }\mathrm{m }{\mathrm{s}}^{-1}$at an angle of${60}^{\mathrm{o}}$with the source observer line as shown in the figure. The observer is at rest. The apparent frequency observed by the observer (velocity of sound in air$330\mathrm{ }\mathrm{m }{\mathrm{s}}^{-1}$) is
