Changing Polarization of Light

Caption

The direction that a light wave is oscillating changes as the wave is reflected by a sheet of graphene. This changing direction of oscillation -- also known as polarization -- enabled researchers to identify the electronic properties of multiple sheets of graphene stacked atop one another -- even when they were covering each other up.
