EXPERIMENTS IN FLUIDS

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 beam that is transmitted in the direction perpendicular ... more

Objective: Investigate the fundamental characteristics of stationary and laminar flowing liquids by using the ultrasonic Doppler method The applications of the Doppler Effect in the medical diagnostics are at the investigation of running ... more

Objective: Investigating a model arm Doppler sonography uses the Doppler Effect to assess whether structures (usually blood) are moving towards or away from the ultrasonic probe, and its relative velocity. By calculating the frequency shift ... more
