Light Waves: Seeing is Believing

As part of Cambridge Science week 2016 I gave a talk at the Cambridge Hands-on Science event: 'Crash Bang Squelch'.

The talk showed, through experimental demonstration, that light exhibits wave-like properties. A shive wave machine, moiré patterns and a metal slinky were used to discuss these properties (including polarisation and interference). Diffraction gratings and polarisation filters were then used to demonstrate that light behaves analogously.
