Practical - Diffraction
Taking large measurements in the lab allows you to calculate the tiny wavelength of light.
1. Diffraction Grating
Using a diffraction grating to investigate, and measure, the wavelength of laser light.
2. Diffraction Grating - Results
An analysis of some typical data taken from a real experiment, to verify the value quoted for the wavelength of a red laser.
3. Lasers - Teacher and Technicians Guidance
A few extra notes for teachers and technicians who will be planning this practical for their classes.
