The optical bench has separate packaging.
Methodological support
The kit has a methodological manual in Russian, which contains instructions for performing 22 experiments.
The description of the experiments is accompanied by optical diagrams and photographs of the assembled setups.
Software for conducting computational modeling
The software allows simulating the diffraction of light on a single slit and on a diffraction grating.
The calculation model "Diffraction of light on one slit" of the software provides calculation of the diffraction pattern appearing on the screen when the slit is illuminated with monochromatic radiation. The on-screen interface of the software provides input of the values of the radiation wavelength and the width of the slit on which diffraction is observed.
The calculation model "Diffraction grating" of the software provides calculation of the interference pattern appearing on the screen when the diffraction grating model is illuminated with monochromatic radiation. The on-screen interface of the software provides input of the values of the radiation wavelength, the number of lines and the period of the diffraction grating model.
Both computational models have electronic methodological manuals describing numerical experiments that can be performed using this model.
