Question

1.4) 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 1

Answer:

As the solid has same value of refractive index along all directions, it is isotropic in nature and hence amorphous. Being amorphous solid, it will not show a clean cleavage and when cut, it will break into pieces with irregular surfaces.

Answer 2

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.
