What is the reflectivity of a glass surface (n =1.5) in air (n = 1) at an 45° for (a) s-polarized light and (b) p-polarized light?

a)

b)

Explanation:

given,

n =1.5 for glass surface

n = 1 for air

incidence angle = 45°

using Fresnel equation of reflectivity of S and P polarized light

using snell's law to calculate θ t

a)

b)

overcharge is the right answer system

pretty sure it's false
