Principle
An echoscope is used to investigate the difference between a spectrum produced by a pulse and a spectrum produced by a periodic signal using multiple reflections from a block. The periodic spectrum allows the cepstrum (Fourier transform of the log spectrum) to ...
A vessel containing liquid is rotated about an axis. The liquid surface forms a paraboloid of rotation, the parameters of which will be determined as a function of the angular velocity.
Tasks
On the rotating liquid surface, the followin ...
A stationary ultrasonic wave in a glass cell full of liquid is traversed by a divergent beam of light. The sound wave length can be determined from the central projection of the sound field on the basis of the refractive index which changes with the sound pressure.
The sound waves transmitted to a liquid by the ultrasonic generator are picked up by a piezoelectric ultrasonic pick-up and the signal from transmitter and receiver compared on an oscilloscope. The wavelength is determined and the phase velocity calculated from the ...
Sound waves are radiated into a liquid by an ultrasonic transmitter and detected with a piezoelectric transducer. The wavelength of the sound is found by comparing the phase of the detector signal for different sound paths and, when the frequency is known, the veloc ...
This experiment provides training in determining the length and position of an object based on an X-ray image. A metal pin that is embedded in a wooden block is used as the model. This experiment is also an excellent preparatory exercise for demonstra ...
