Product description:
A set of optical devices to demonstrate the diffraction and interference of light and to obtain its spectrum. The analysis of the location of light and dark diffraction stripes makes it possible to determine the length of the wave falling onto the grating.
All the diffraction gratings are made of a plastic frame (5 x 5 cm) and foil (35 x 23 cm) with openings of different shapes and spacing. They can be mounted on special stands or optical benches.
The set consists of 5 gratings:
- with 3 single slits (width 0.05, 0.1, 0.2 mm);
- with 3 double slits of 0.05 mm (spacings 0.2, 0.3, 0.45 mm);
- with single slits, 2 slits, 3 slits, 4 slits, multiple lines (30 and 60 lines/mm, circular apertures (D 0.36 mm), triangular apertures (side 0.3 mm), square apertures (side 0.2 mm), rectangular apertures (0.6 x 0.28 mm); all slits 0.06 mm wide with spacing 0.05 mm;
- with 3 rectangular apertures, each formed by lines intersecting at right angles; number of lines: 20, 40 and 60 respectively;
- with round apertures of diameters 0.2, 0.3, 0.4 mm;
Weight: 0.02 Kg
