Diffraction of light through a double slit or by a grid with optical base plate

Product No: P2230405

Principle

The coherent monochromatic light of a laser is directed to a diaphragm with a varying number of slits. The resulting interference patterns are studied using a photoelement.

Tasks

The intensity distribution of diffraction patterns formed by multiple slits is mesasured using a photoelement.
The dependence of this distribution from the slit widths, the number of slits and the grid constant is investigated.
The obtained curves are compared to the theoretical values.
