What fraction of light reflected when the optical constant of silver metals at a wavelength of 0.55um is 0.055. take K (index of absorption) 3.32

. Calculate the thickness of silver wire when 50 % transmitted of incident light take place

Incident beam Reflected beam Incident beam Reflected beam o Medium 1 Medium 1 (e.g., air) n, (1) n. (2) Medium 2 (e.g., glass) Medium 2 1 Blue 1 Red Retracted beam A B Retracted beam 3 Optical effects at the incertace between media possessing different refractive indices. (A) Depiction of Snell's law. Light travels fascer in low-index medium. (B) Dispersion of light. Red light travels slightly faster than light of shorter wavelength, and is bent or dispersed less
