A) Velocity of sound towards the source
B) Velocity of sound away from the source
C) Half the velocity of sound towards the source
D) Double the velocity of sound towards the source
Correct Answer: A
Solution :
By using \[{n}'=n\,\left( \frac{v}{v-{{v}_{S}}} \right)\] \[2n=n\,\left( \frac{v-{{v}_{O}}}{v-0} \right)\] Þ \[{{v}_{O}}=-v=-\](Speed of sound) Negative sign indicates that observer is moving opposite to the direction of velocity of sound, as shownYou need to login to perform this action.
