Diffraction Grating with White Light

$Slide projector with diffraction grating attached to lense$

Concept Overview:

1. White Light Diffraction

Lecturer Procedures

Step(s) to Follow	Expected Result
Turn projector to "on" position and note results	Continuous spectrum is produced on opposite sides of white slit (see below)
Take care not to turn on the automatic advancing function, or slit will be ejected from projector

Expected Result

Turn projector to "on" position and note results

Continuous spectrum is produced on opposite sides of white slit

(see below)

Take care not to turn on the automatic advancing function, or slit will be ejected from projector

$Continuous spectrum created through the diffraction of white light$

This is often requested in conjunction with L: W - 6 Dispersion by a Prism. Please specify if you would like both.
