Maxwell's equations explain It beautifully without magic. |
Reflectivity is a function of many variables, including: angle of incidence, refractive index of the medium, surface finish, surface treatment, coating, wavelength, etc.... The thickness/number/order of individual layers in the multicoating are chosen to help promote destructive interference in the reflected light and constructive interference in the transmitted light at the interface/s.
