Experiment set WAVES

Wave phenomena in ultrasonics

The characteristic wave properties of interference, diffraction and standing waves, along with reflection and refraction, can be particularly easily learned, clearly, quickly, impressively and with high precision in experiments carried out by students themselves. The equipment provides various experimental methods for determining wavelength.

Extreme precision

The key component of this experiment set is a central control unit. It provides not only two synchronously oscillating transmitters but also sends the signal from the receiver to a display. It also supplies all the power needed via its 9 V block battery. The unusually high accuracy of the experiment results arise from the sophisticated electronics and in particular from the mirror scale on the base plate and the transparent acrylic scales, which allow readings to be made to an accuracy of half a degree or half a millimetre.

Possible enhancements

Diffraction by a grating cannot be demonstrated using this experiment set. Polarisation is naturally omitted also. Both these two wave phenomena can, however, be investigated very impressively using the OPTICS 3 plus experiment set.
