ЭКСПЕРИМЕНТЫ УЛЬТРАЗВУК

Equipment set for experiments on geometric and wave-mechanical acoustics. Based on the piezo-effect discovered by the Curie brothers, an AC voltage is applied to a piezo-electric body causing it to oscillate. Sound waves can also be used ... еще

ЦЕЛЬ ОПЫТА Определение скоростей звука, распространяющегося в виде продольных и поперечных волн в твердых телах КРАТКОЕ ОПИСАНИЕ В твердых телах звук распространяется в виде продольных и поперечных волн. Однако имеется существенная р ... еще

ЦЕЛЬ ОПЫТА Определение скорости ультразвуковых волн в жидкостях КРАТКОЕ ОПИСАНИЕ Периодические изменения плотности, вызванные стоячей ультразвуковой волной в жидкости, работают как оптическая дифракционная решетка для монохроматическ ... еще

Objective: Determining the internal dimensions in a model eye Sonography (medical ultrasound) is an imaging method that is also used in ophthalmology. Here, its largest importance lies in the area of biometry, in the measurement of distances ... еще

Objective: Investigate the formation of an ultrasonic CT image and its relevant parameters X-ray CT, MRT and PET are computer-aided imaging methods used in medical diagnostics, industry and research. Processes such as radiation absorption ... еще

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 ... еще

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 ... еще
