Polarised light is when the light wave is vibrating on one plane.

Polarisation is when the light wave is transformed from unpolarised to polarised light.

Using sunglasses is an example of polarising light.

Unpolarised light is when a light wave is vibrating in more than one plane - eg light from a light fitting or the sun.

Meet Pola Polarise!

When light is refracted it is polarised.

 When light is reflected it will also change.

Looking through glass will change the light

A tinted glass like sunglasses will change the light also.
