Spectral resolving power of a grating

Article no: P1196700

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

  1. on the number of active grating slits and
  2. on the order of the diffraction spectrum.
