A student holds a tuning fork ocillating at 2456 Hz. He walks towards a wall at a constant speed of `1.33(m)/(s)`. (a) What beat frequency does the student observes between the tuning fork and its echo? (b) How fast must he walk away from the wall to observe a beat frequency of `5.00Hz`?

A student holds a tuning fork oscillating at 170 Hz. He walks towards a wall at a constant speed of 2 ms^(-1) The beat fequency observed by the student between the tuning fork and its echo is (Velocity of sound =342 ms ^(-1) )

There is a source of sound (a tuning fork) moving towards a reflecting wall will a speed of 30 ms^(-1) . The velocity of the sound in air is 330 ms^(-1) and the frequency of the tuning fork is 600 Hz. The observer is between the source and the wall and is moving with some velocity V_(1) towards the wall. The beat frequency heard by the observer is 4 Hz. If the tuning fork is waxed, the frequency beats heard by the observer becomes 3 Hz. If the new frequency of tuning fork is k then k//50 is

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. Suppose that a listener is located at rest between the tuning fork and the wall. Number of beats heard by the listener per second will be
