The wave nature of light. Experiments

The experiments are carried out by Maxim Belokon and Alexei Bespalkov. 

The experiments show the wave nature of light and demonstrate the phenomena that confirm its validity, such as interference, diffraction, dispersion and polarisation.

Diffraction of monochromatic light by a one-dimensional grating

Diffraction of monochromatic light by a two-dimensional structure

Rotation of the plane of polarisation in a sugar solution

Adding spectral colours

Splitting natural light into a spectrum with a diffraction grating

Polarisation of light

Polarisation of light reflected from a dielectric

Absorption of light in matter

Monochromatic light cannot be split into a spectrum
