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 ...

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 ...

Objective: Generate and measure standing sound waves in Kundt’s tube
Sound 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 ...

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 ...

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 ...

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 ...
