Principle

This experiment on diffraction at an optical grating not only
provides convincing proof of the ability of (visible) light to
undergo interference, and hence of its wave character; but it is
also well suited to determine the wavelength of selected colours of
the spectrum. Moreover, it is sure to motivate students who will be
impressed by the ability to determine with simple means such small
physical quantities as the wavelength of light.

Benefits


Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench

Extension with others sets at anytime, no additional light sources needed, recognition value for students



Tasks

Produce a diffraction spectrum using an optical grating and
determine the wavelengths of red and green light.
