Diffraction on a system of slits and diffraction grating. 2.3.04-00

Get the concept of:
Huygens' principle, law of interference, Fraunhofer and Fresnel, coherence, laser

Experiment:
The system of slits of equal width and the distance between each other, as well as diffraction gratings with different lattice constants highlights laser beam. With the help of rolling photodiode corresponding diffraction patterns are studied.
