A car is moving towards a huge wall with a speed \( =\mathrm{c} / 10 \), where \( \mathrm{c}= \) speed of sound in still air. A wind is also blowing parallel to the velocity of the car in the same direction and with the same speed. If the car
P sounds a horn of frequency \( \mathrm{f} \), then what is the frequency of the reflected sound of the horn heared by driver of the car?
