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 wave of wavelength 0.60 cm is produced in air and it travels at a speed of 300 ms^-1. Will it be audible?

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) .
