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?

Explanation

The solid is isotropic in nature (Same value of refractive index along all directions). An amorphous solid is isotropic. Hence, the solid is amorphous and so it does not show clean cleavage when cut with sharp edged knife. Instead, it undergoes irregular breakage and forms pieced with irregular surfaces.
