Master Questions on the Diffraction Grating Practical - Measure Wavelength of Laser Light
Channel: Kit Betts-Masters
Date: 2020-05-19

This is the Diffraction Grating Core Practical, PAG or Required Practical it's the same in all exam boards.   The aim is to Measure Wavelength of Laser Light.
I also go through the variation for the Young's Double slit interference practical and the slight change to the method to allow you to be accurate with both procedures.
