Which consequence results when unpolarized light strikes dichroic mineral tourmaline?

A)Parallel-wave transmission occurs
B)Refractive index becomes isotropic
C)Optical activity gets reversed
D)Chromatic aberration is minimized

💡 Explanation

Parallel wave transmission occurs because tourmaline exhibits dichroism; it absorbs light with electric vectors in one direction, allowing only the parallel component to pass via selective absorption. Therefore strong plane polarization results, rather than isotropic refraction or reversing optical activity, as dichroism is about absorption differences.
