In Quincke's experiment on interference of sound a turning fork of frequency `540 Hz` is used. Calculate the distance by which the sliding tube is to be drawn out to pass from one minimum to the next minimum.
(Velocity of sound `=350 m s^(-1)`)

A tuning fork of frequency 440 Hz is to be mounted on a wooden box with one end open to reinforce its sound. What would be the length of the sounding box ? (Velocity of sound in air = 332 ms^(-1) )

Calculate the distance that sound travels in air when a tuning fork of frequency 250 Hz makes 44 vibrations. Take, velocity of sound in air = 320 m/s.

The minimum distance to hear an echo is (Taking the velocity of sound in air to be 330 m s^(-1) )

A siren emiting sound of frequency 800Hz is going away from a static listence with a speed of 30 m//s frequency of sound to be beand by the listener is ("velocity of sound" = 330 m//s)

In Quincke's experiment, the sound intensity has a minimum value I at a particular position. As the sliding tube is pulled out by a distance of 16.5 mm, the intensity increases to a maximum of 9 I. Take the speed of sound in air to be 330 m s^-1. (a) Find the frequency of the sound source. (b) Find the ratio of the amplitudes of the two waves arriving at the detector assuming that it does not change much between the positions of minimum intensity and maximum intensity.

A tuning fork of frequency 340 Hz is vibrated just above the tube of 120 cm height. Water is poured slowly in the tube. What is the minimum height of water necessary for the resonance? (speed of sound in the air = 340m/s)

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) )

A tuning fork of frequency 250 Hz is vibrating at one end of a tube as shown in the figure. If maximum sound is heard at the other end, then the velocity of the waves will be

Distance travelled by the sound produced by a tuning fork of frequency 50 Hz completing 200 vibrations is, (the velocity of sound in air is 330 m/s)
