Which of the following is false about polarization of light?
It explains the separation of colors in white light by a
prism.
It can arise in reflection or scattering of light.
The intensity of a light wave by itself does not give any
information about the wave’s
polarization.
It arises because electric and magnetic fields in waves can have
components...
