Polarisation of Waves - A Level Physics

In the video I explain the polarisation of waves (including the polarisation of light) for A Level Physics.

Only transverse waves can be polarised, this video explains why. It also shows why sunglasses are known as 'polaroids' and how you can test this yourself on a sunny day.

Update - Please note that the reflected light waves from water are actually horizontally polarised:
