Brewster’s law is defined as the light which receives maximum polarization from a reflecting surface when it is incident to the surface at an angle such that the tangent is equal to the index of refraction.
The law is mathematically given as:
|μ = tan ip|
- μ is the refractive index of the surface
- ip is the polarizing angle of incidence
According to Brewster’s law μ = tanθ, = tan60o = √3
