Polarization

1
Polarization
2
Linear and Circular Polarization
3
Circular case occurs when the x and y components
are out of phase
4
Random Polarization or Unpolarized
Unpredictable polarization on any time scale you
can readily measure
5
Unpolarized light loses half its intensity
on passing through a polarizer. Malus Law
applies if it then goes through a second one.

Natural Sources

• Crystals
• Reflection
• Scattering

Reflection of Orthogonal components of E field

• Parallel case No reflection if
