Practical - Diffraction

Taking large measurements in the lab allows you to calculate the tiny wavelength of light.

1. Measuring the Wavelength of Light with a Diffraction Grating

A laser will also diffract and interfere when shone through a diffraction grating.  The distance to the first, second and third order maxima can be measured which will then allow the wavelength of the light to be calculated.

Take care with the laser!
