It, like the TIR critical angle, depends only on the materials' refractive indexes.

You can move the blue points, and select what is displayed, and what is hidden. Use this sketch to play around with reflection. Brewster's angle is a special incidence angle which results in P polarized being completely transmitted (i.e. Reflection, Geometric Transformations Exploring reflection. TIR can occur only if material 2 has a lower refractive index than material 1 and even then the incidence angle must be larger than a so called critical angle. For convenience, the calculator also computes an average result corresponding to unpolarized light.Īdditionally, this calculator computes the refraction angle, the angle for total internal reflection (TIR) and Brewster's angle. Therefore, the results are different for S polarization (E-field vector sticking out of the paper if you draw the interface) and P polarization (E-field vector within the incidence plane). These depend on the refractive indexes of the two materials as well as the incidence angle and polarization of the wave in material 1.
Eulerian Kappa geometry converter This shows the corresponding angles.
