Unformatted text preview: olarization is defined as the direction of the
electric field. Linear polarization, circular
polarization, elliptical polarization.
= cos ∙− = cos ∙− = From Faraday’s Law, the total

= cos ∙− must be continuous across the interface or
on the other side.
The law of reflection
sin = sin How polarization effects the reflection and transmission
of light at an interface.
Consider the case shown to the right, the electric field is
perpendicular to the plane of incidence, the continuity
