unpolarised การใช้

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.
