Refractive index of a solid is observed to have the same value along all directions. Comment on the nature of this solid. Would it show cleavage property?

Answer»

Solution :As the solid has same value of REFRACTIVE index along all directions, this means that it is isotropic and hence amorphous. Being an amorphous solid, it WOULD not show a clean cleavage when cut with a knife. Instead it would break into PIECES with irregular SURFACES.
