Zeeman effect with a variable magnetic system

Item no.: P2511007 Principle The “Zeeman effect” is the splitting up of the spectral lines of atoms within a magnetic field. The simplest is the splitting up of one spectral line into three components called the “normal Zeeman effect”. In this experiment the normal Zeeman effect as well as the anomalous Zeeman effect are studied

Faraday effect

Item no.: P2260100 Principle The angle of rotation of the polarisation- plane of plane polarised light through a flint glass rod is found to be a linear function of the product of the mean flux-densitiy and the length of the optical medium. The factor of proportionally, called Verdet’s constant, is investigated as a function of

Doppler effect with the Michelson interferometer

Item no.: P2221000 Principle With the aid of two mirrors in a Michelson arrangement, light isbrought to interference. While moving one of the mirrors, the alterationin the interference pattern is observed and the modulation frequency is measured using the Doppler effect. Tasks Construction of a Michelson interferometer using seperate components. Measurement of the Doppler effect via

Radiographic examination of objects

Item no.: P2540020 Principle An X-ray tube produces X-rays that cause a fluorescent screen to emit light. Objects that are located between the X-ray source and the fluorescent screen will be irradiated so that their inner structure becomes visible. If one varies the anode current and voltage, the change in intensity can be observed in

Fine structure of the alpha spectrum of Am-241 with MCA/ alpha spectroscopy

Item no.: P2522215 Principle The alpha-spectrum of an open 241Am-emitter is measured with a semiconductor a-detector. In connection with a multi channel analyzer the main parts of the spectrum are investigated. Tasks The spectrum of an uncovered 241Am-emitter is recorded with the multi channel analyzer. The energies of the two peaks preceding the principal peak are calculated. The
