a) Consider a light wave traveling through air and reflecting, at normal incidence, from a nonmagnetic glass plate. The refractive index of air is nair and the refractive index of the plate is nglass. If nglass>nair, is the reflection coefficient positive or negative? (The refractive index of a nonmagnetic material is related to the relative permittivity by n² = €₁.) b) Let's consider another light wave traveling through air and hitting, at an incident angle of 8, a nonmagnetic glass plate. The refractive index of air is nair and the refractive index of the plate is nglass. When the light wave hits the glass, some of the light transmits at an angle 8, (relative to the surface normal of the glass). If nglass nair is e, greater than or smaller than 8,?

a) Consider a light wave traveling through air and reflecting, at normal incidence, from a nonmagnetic glass plate. The refractive index of air is nair and the refractive index of the plate is nglass. If nglass > nair is the reflection coefficient positive or negative? (The refractive index of a nonmagnetic material is related to the relative permittivity by n² = €₁.) b) Let's consider another light wave traveling through air and hitting, at an incident angle of 0, a nonmagnetic glass plate. The refractive index of air is nair and the refractive index of the plate is nglass. When the light wave hits the glass, some of the light transmits at an angle 0, (relative to the surface normal of the glass). If nglass>nair is ₂ greater than or smaller than 0,?
