λ/2-plate (Half wave plate): It produces a phase difference of ΔΦ = (λ/2) * (2π/λ) = π Thickness: t = λ / (2 * (n_e - n_o)) C.P → R.C.PR.C.P → L.C.PR.E.P → L.E.PP.P → P.PU.P → U.P Ques. 5 λ = 600 nm = 600 × 10⁻⁹ m t = λ / (2(n_e - n_o)) = 600 × 10⁻⁹ / (2(1.55 - 1.54)) = 30 μm If L.C.P → P.P t = 4λ / (n_e - n_o) = 15 μm Ques. 17 Mirror (conducting surface) Δφ = 180° in reflected wave Then, Left Circularly Polarized (option-c) Ques. 18 θ = 90° φ = 45° Out-put wave: Negative helicity
