    A small laser is used to simulate x-ray diffraction using two diffraction gratings oriented vertical and horizontal grid lines.
Safety: 
Be aware of reflections of the laser off of the diffraction gratings.

Description: 

Two diffraction gratings are oriented at right angles and a small lecture laser projects a pattern of dots similar to x-ray diffraction.

Purpose: 
Show how crystal lattices can be determined by x-ray diffraction techniques.
Parts: 


Two 600 lines/inch diffraction gratings.
lecture laser.
