Degree of Polarization: if Oc = Ob, R11 = 0 -> Completely Plane Polarized Light. P = (R1 - R11) / (R1 + R11) if R11 = 0 -> P = 1 -> Completely P.P. if R1 = R11 -> P = 0 -> Unpolarized 0 < P < 1 -> Partially P.P. Mathematical Equations: Eor / Eoi = (m1 - m2) / (m1 + m2 - i*mp) if m1 = -ve (Real) then delta = TT Eor / Eoi = (i*ip + (i*ip - i*ip)) / ((2 + i*ip) * (2 - i*ip)) = (-2*ip - p^2) / (4 + p^2) Phase Difference: tan(Δφ) = (-2ρ) * (4 + ρ^3) / (-ρ^2 * (4 + ρ^2)) Δφ = tan^-1(2/ρ) Phase difference E & B inside the Conductor = ? nz = m(1 + iρ) if K is complex, K^μ = α + iβ then φ = tan^-1(β/α) Speed of Wave: v = c/n = ω/k n = (ω/k) n ∝ k Phase Difference between E & B: φ = tan^-1(ρ/1) = tan^-1(ρ) Reflection and Refraction: (n2 > m1) -> Rare to Denser if Oi = Os then reflected intensity is minimum. if unpolarized wave then -> R1 = R11 if Oi = Ob then R11 = 0 Oi = Ob = tan^-1(m2/m1) # Under What Cond? Transmitted intensity is minimum -> Oi >= Oc Oc -> critical angle of incidence T = 0 it is valid only if m2 < m1
