Assignment

1. Find the velocity of 2 MHz ultrasonic wave through water using ultrasonic interferometer.
2. A sound wave of frequency 2 MHz propagates through a medium of acetone. Calculate the velocity with which the wave travels and also find the adiabatic compressibility of acetone.
3. Using the device ultrasonic interferometer, calculate the adiabatic compressibility of water, castor oil, and glycerin. Compare the results and comment.
4. Calculate the velocity of propagation of a 2 MHz pressure wave through a medium of kerosene. Also calculate the adiabatic compressibility of kerosene.
5. Using ultrasonic interferometer, calculate the density of castor oil. Given, the adiabatic compressibility of the medium is 4.813×10⁻¹⁰ m²/N.
