Question: The source producing sound and an observer both are moving along the direction of propagation of sound waves. If the respective velocities of sound, source and an observer are v, ${{v}_{s}}$ and ${{v}_{o}}$, then the apparent frequency heard by the observer will be (n = frequency of sound)


1) $\frac{n(v+{{v}_{o}})}{v-{{v}_{o}}}$
2) $\frac{n(v-{{v}_{o}})}{v-{{v}_{s}}}$
3) $\frac{n(v-{{v}_{o}})}{v+{{v}_{s}}}$
4) $\frac{n(v+{{v}_{o}})}{v+{{v}_{s}}}$
Solution: Explanation: No Explanation
