A boy riding on his bike is going towards east at a speed of m s^-1. At a certain point he produces a sound pulse of frequency 1650 Hz that travels in air at a speed of 334 m s^-1. A second boy stands on the ground 45^o south of east from him. Find the frequency of the pulse as received by the second boy.
The second boy is at a 45° angle.

So, the velocity of the source will be,

Hence, the apparent frequency will be,
