  • A beam of unpolarised light can be thought of as containing a uniform mixture of linear polarizations at all possible angles.
  • For "'unpolarised "'physics, mostly liquid hydrogen is used, allowing to study the proton properties.
  • :: : In general, the ground is uncharged / unpolarised, and thus won't be affected by a magnetic field.
  • Schuko sockets are unpolarised, there is no way of differentiating between the two live contacts ( line which is approximately 230 V to earth and neutral which is approximately 0 V to earth ) unless the voltage to earth is measured prior to use.
  • In practice, some light is lost in the polariser and the actual transmission of unpolarised light will be somewhat lower than this, around 38 % for Polaroid-type polarisers but considerably higher ( > 49.9 % ) for some birefringent prism types.
  • For example, the CEE 7 / 7 plug has been adopted in several European countries and is compatible with both CEE 7 / 3 and CEE 7 / 5 sockets, while the unearthed and unpolarised CEE 7 / 16 Europlug is compatible with even more European and other socket types.
