An aluminium rod having a length of 90.0 cm is clamped at its middle point and is set into longitudinal vibrations by stroking it with a rosined cloth. Assume that the rod vibrates in its fundmental mode of vibration. The density of aluminium is 2600 kgm^-3 and its Young's modulus is 7.80xx10^10 Nm^-2 . Find a. The speed of sound in aluminium, b. The wavelength of sound waves produced in the rod. c. The frequency of the sound produced and d. The wavelength of the sound produced in air. Take the speed of sound in air to be 340 ms^-1 .

A sound has a frequency of 60 Hz and a wavelength of 20 m. What is the speed of the sound?

A SONAR system fixed in a submarine operates at a frequency 40.0kHz. An enemy submarine moves towards the SONAR with a speed of 360km h^(-1) . What is the frequency of sound reflected by the submarine ? Take the speed of sound in water to be 1450ms^(-1) .

Sound waves from a loudspeaker spread nearly uniformly in all directions if the wavelength of the sound is much larger than the diameter of the loudspeaker. (a) Calculate the frequency for which the wavelength of sound in air is ten times the diameter of the speaker if the diameter is 20 cm. (b) Sound is essentially transmitted in the forward direction if the wavelength is much shorter than the diameter of the speaker. Calculate the frequency at which the wavelength of the sound is one tenth of the diameter of the speaker described above. Take the speed of sound to be 340 m s^-1 .
