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: https://sureshemre.wordpress.com/2014/01/02/light-reflecting-off-water-is-polarized/ https://www.osapublishing.org/DirectPDFAccess/70EF21F6-C0C6-DC00-994222A32CB6DCEF_276371/oe-21-26-32549.pdf?da=1&id=276371&seq=0&mobile=no
