1.	Refractive index of a solid is observed to have the same value along all directions. Comment on the nature of the 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
