The invention provides a Doppler Effect experimental device. The device comprises a first pool, a second pool, a pump, a tube, a groove, a vibration source and liquid substances. The invention also provides a Doppler Effect experimental system, the Doppler Effect experimental device and control equipment, wherein the control equipment comprises a control circuit, a control panel, a light source and a box. The invention also provides a Doppler Effect experimental method in which an experiment is carried out by using the Doppler Effect experimental system. The Doppler Effect experimental method comprises the following steps of: continuously transporting the liquid substance in the first pool to the second pool through the tube so that the liquid substance in the second pool continuously flows back to the first pool through the groove so as to form a continuous liquid flow in the groove; vibrating by using the vibration source to touch the liquid level of the continuously flowing liquid in the groove; and acquiring an upstream wavelength of the vibration source and a downstream wavelength of the vibration source. The device, the system and the method can continuously demonstrate the Doppler Effect for a long time.
Description
technical field [0001] The invention relates to the technical field of educational experimental supplies, in particular to a Doppler effect experimental device, system and method. Background technique [0002] The Doppler effect is a subject that must be studied by scholars in many fields. It is very necessary and effective for students who have a preliminary understanding of the Doppler effect to demonstrate the Doppler effect intuitively through experimental instruments. [0003] The existing method of demonstrating the Doppler effect is to demonstrate by moving the vibration source on the liquid surface and observing the change of the wavelength of the water wave on the liquid surface. [0004] However, the inventors found that because the space in the laboratory is mostly limited, the container holding the liquid is small, and the movable distance of the vibration source is often very limited, resulting in a very short Doppler phenomenon, which cannot last for a long tim...
