In this workshop we'll go through a few optical components you can build with easily obtainable supplies, including diffraction gratings, integrating spheres, and (hopefully- it's quite difficult to make) even a Fabry-Perot etalon. I'll demonstrate how to set up a few cool optical experiments, including a physical Fourier Transform, and measuring the speed of light. If anyone's interested, I'll also talk them through the derivation of the speed of light from Maxwell's equations.
