Physics - Sound Wave Question with Solution | TestHub

Consider the vehicle emitting sound wave of frequency$700\mathrm{ }\mathrm{Hz}$moving towards an observer at a speed$22 \mathrm{m} {\mathrm{s}}^{-1}$. Assuming the observer, as well as the medium to be at rest and velocity of sound in the medium to be$330 \mathrm{m} {\mathrm{s}}^{-1}$, the frequency of sound as measured by the observer is
