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 :



An isotropic solid has
 the
same value of physical properties when measured along different directions.
Therefore, the given solid, having the same value of refractive index along all
directions, is isotropic in nature. Hence, the solid is an amorphous solid.



When an amorphous solid is cut with a sharp edged tool, it cuts into two pieces
with irregular surfaces.
