If the light that has been reflected from the wall into the water is observed to be completely polarized, what angle does this beam make with the normal inside the water

Respuesta :

The angle of incidence for a complete polarization of incident ray on water is 53.1⁰.

The given parameters;

  • refractive index of water, μ = 1.333

The angle of incidence for a complete polarization of incident ray on water is calculated by applying Brewster's law as shown below;

[tex]\mu = tan \ \theta[/tex]

where;

  • θ is the polarizing angle

The polarizing angle is calculated as;

[tex]\theta = tan^{-1}(1.333)\\\\\theta = 53.1^ 0[/tex]

Thus, the angle of incidence for a complete polarization of incident ray on water is 53.1⁰.
