It is applicable not only to isotropic transparent, translucent, coloured or opaque materials but also to anisotropic materials. \u2014 Method B: an immersion method (making use of the Becke line phenomenon) for determining the refractive index of powdered or granulated transparent materials by means of a microscope.
