1.	Refractive index of a solid is obseved to have the same value along alll directions. Comment on the nature of the soild. 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 ans amorphous solid, it would not show a clean cleavage when CUT with a knife. Instead, it would break into PIECES with IRREGULAR surfaces.
