Principle

In order to assess the spectral resolving power of an optical
grating we utilize the quotient a/0~,. This quotient can only be
determined accurately if we can create a line spectrum containing
lines at suitable distance &. apart. However, even with fairly
simple means it is possible to arrive at statements an the spectral
resolving power of a grating which are sufficiently informative for
school pupils.

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

Investigate to what extent the resolving power of a grating
depends


on the number of active grating slits and


on the order of the diffraction spectrum.
