In a Kundt's tube experiment it was found that the distance between nodes was 6.6 cm when the sounding rod used was of total length 80 cm. Calculate the velocity of sound in the rod if velocity of sound in air `330 ms^(-1)`.

At one end of a steel bar of 1 kilometre length, a source of sound is placed and two sounds are heard at the other end at an interval of 2.74 seconds. Calculate the velocity of sound in steel if velocity of sound in air is 340 ms^(-1) .

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

In a Kundt's tube experiment a brass rod 120 cm long was used. If had a fundamental frequency of 1400 Hz . The gas in the tube was CO_(2) at 20^(@)C and the disatance between nodal heaps of powder was found to be 9 cm. Calculate the velocity of sound in brass and in CO_(2) at 0^(@)C .

In Quincke's experiment the sound detected is changed from a maximum to a minimum when the sliding tube is moved through a distance of 2.50 cm. Find the frequency of sound if the speed of sound in air is 340 m s^-1 .

The sounding rod of a dust tube apparatus is made of brass and is 160 cm long. The distance between adjacent nodes in the wave tube was 11.35 cm. Calculate the Young's modulus of the rod assuming that velocity of sound in air at room temperature is 350 ms^(-1) and density o fbrass 900 kg m^(-3)

A tuning fork of 512 Hz is used to produce resonance in a sresoncance tube experiment . The level of water at first resonance is 30. 7 cm and at second resonance is 63 . 2 cm . The error in calculating velocity of sound is (speed of sound in air = 330 m/s)
