Light - A Transverse Wave

16th May is the International Day of Light

The talk will introduce light as a transverse electromagnetic wave, a very very short wavelength radio wave. The direction of the electric field gives the light polarisation, something we know through polarising sunglasses and computer screens. Examples of polarised light in nature, science and technology will be presented and discussed.
