A beam of unpolarized light in a medium with dielectric constant {\epsilon }_{1} is reflected from a plane interface formed with another medium of dielectric constant {\epsilon }_{2}=3{\epsilon }_{1}. The two media have identical magnetic permeability. If the angle of incidence is {60}^{\circ }, then the reflected light

A beam of unpolarized light in a medium with dielectric constant

ϵ_{1}

is reflected from a plane interface formed with another medium of dielectric constant

ϵ_{2} = 3 ϵ_{1}

. The two media have identical magnetic permeability. If the angle of incidence is

60^{\circ}

, then the reflected light

1is plane polarized perpendicular to the plane of incidence
2is plane polarized parallel to the plane of incidence
3is circularly polarized
4has the same polarization as the incident light
