What is the difference between coherent light and polarized light?
If I understand this correctly coherent light means that the waves are syncronized(in phase) and they have exactly the same wave length.
Polarized light means the waves have only one direction - the direction of the polarization.
In polarized light the waves do not have the same length and the waves are not in phase.
Coherent light is polarized, but polarized light is not coherent.
