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)` )

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 tuning fork of frequency 380 Hz is moving towards a wall with a velocity of 4(m)/(s) Then the number of beats heard by a stationary listener between direct and reflected sound will be (velocity of sound in air is 340(m)/(s) )

A tunning fork of frequency 512Hz approaches a wall with a velocity of 4ms^(-1) . How many beats are produced between the direct and the reflected sound if the velocity of sound is 332 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

The frequency of a tuning fork is 600 Hz. What is the number of vibrations made by the tunning fork, when the sound produced by the tuning fork travels a distance of 110 ? (Velocity of sound in air is 330 ms^(-1) )

Figure shows a person standing somewhere in between two identical tunning forks, each vibrating at 512 Hz. If both the tuning forks move towards right at a speed of 5.5 ms^-1 , find the number of beats heard by the listener. Speed of sound in air =330 ms^-1 .
