Le prisme

The animation "Prism" is used to study the dispersion of white light through a prism (you can choose between three different index prisms).
We can also illuminate the prism with monochromatic light whose wavelength ranges from 400 to 700 nm. In this case, the index of the prism as a function of the light wavelength monochromatic is displayed on the prism and an option is provided to display the different angles.
