If the light is reflected by a glass pane it is polarised i.e.
the degrees of freedom of the vibration are restricted and the wave
then only vibrates in a single direction. If such polarised light
falls onto a polarisation filter only allowing light through in one
particular direction of vibration, the intensity of the light is
attenuated or even blocked completely.
How does light vibrate? Light is an electro-magnetic transverse
wave, which means that it vibrates at right angles to the direction
of propagation. Determine the dependency on the angle of the
transmission of a polarisation filter by means of a photodiode.
Determine the relationship between the angle of polarisation and
the intensity of the transmitted light.
