Raman and Rajan were studying the properties of solids. A solid 'X' showed same physical properties (thermal conductivity and refractive index) in all directions while another solid 'Y' showed differrent physical properties in different directions. Raman classified the solid 'X' as crystalline and solid 'Y' as amorphous. Rajan did not agree with Raman's classification. Answer the following questions
Whom do you favour, Raman or Rajan and why?

Answer the following questions What is the natme of the property exhibited by solid 'X'?

Solid which do not show the same physical properties in different directions are called:

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?
