Slit and grating experiments are central methods for investigating diffraction and interference in optics. They enable the clear demonstration of wave-optical effects and are used in areas such as spectroscopy, wave theory and quantum mechanics. Gratings and slits play an important role in physics and technology. They are used in spectroscopy, in the determination of wavelengths and in quantum mechanics, for example in experiments on the wave properties of particles.
The experiment module contains a specially developed grating holder that securely fixes standard experimental gratings, diffraction gratings or slit diaphragms. This allows different grating types to be used and examined flexibly. The combination with a coherent light source, such as a laser diode, enables the visualization of interference patterns and diffraction effects.
On this page you will find all information on possible set-ups of the modular experiments as well as working materials for use in the classroom.
Experiments
- Single-slit diffraction: Analysis of the intensity distribution and angular dependence of the diffraction maxima.
- Double-slit interference: Investigation of the dependence of the interference pattern on the slit width and distance.
- Diffraction at the grating: Determination of the grating constant by analyzing the diffraction order.
- Spectroscopic application: Use of gratings to investigate the spectral composition of light sources.
