Abstract
- Practical teaching experiments on optical Doppler effect are not a simple task, not only by the design but also because the experiment itself have many issues. The main problem is to produce a smooth movement of the light source, for little imperfections, of the order of the wavelength, result in important noises in the final measurements. Using a rotating mirror in which the incident beam is reflected in both the receding and the advancing parts of its surface, allows to minimize noise problems as well as mechanical deviations. The laboratory practice described in this paper can be constructed using low cost parts that are usually found in student laboratories. We also propose some questions and problems to help the teaching to work out this matter. [ABSTRACT FROM AUTHOR]
