Chladni figures-making sound visible   The Chladni figures are named after the German scientist Ernst Florens Friedrich Chladni (1756-1827). Chladni excited the normal modes of thin metal plates covered with sand by stroking ... more

Objective: Measuring the propagation time of sound pulses in Kundt’s tube Sound waves propagate longitudinally in gases. The group velocity here is equal to the phase velocity. In this experiment, we will measure the propagation time of ... more

Objective: Generate and measure standing sound waves in Kundt’s tubeSound waves propagate in gases in the form of longitudinal waves. The overall velocity is equivalent to the phase velocity. In this experiment a standing wave is generated ... more

Objective: Investigation of longitudinal sound waves in cylindrical rods and determination of propagation velocity for longitudinal sound waves Sound waves can propagate through solids in the form of longitudinal, transverse, dilatational ... more

Objective: Determine the speeds of sound propagated by longitudinal and transverse waves in solidsIn solids, sound is propagated in the form of longitudinal and transverse waves. However, there is a considerable difference in the speed ... more

Objective: Determine the velocity of ultrasonic waves in liquids The periodic variations of density caused by an ultrasonic standing wave pattern in a liquid act as an optical grating for the diffraction of a monochromatic parallel light ... more
