As shown if Fig. a vibrating tuning fork of frequency 512 Hz is moving towards the wall with a speed `2(m)/(s)`. Take speed of sound as `v=340(m)/(s)` and answer the following questions.
Q. If the listener, along with the source, is moving towards the wall with the same speed i.e., `2(m)/(s)`, such that the source remains between the listerner and the wall, number of beats heard by the listerner per second will be
