(e) Explain what you understand by the statement: “the bonding in a solid is 30 % ionic and
70 % covalent". Why such types of bondings are occurred in a materials. Give proper
reasoning with examples.
3. (a) One way of treating the vibrational modes of a linear diatomic solid is to assume
that the atoms have the same masses, but the springs on either side of an atom have
spring constants K and G, respectively. Show that the dispersion relation of such a lattice
is given by
(K+G`
+G)' - 4KGsin ka
M
where M is the mass of the ion, G and K the lattice constants, a is the periodic distance
between masses and k the lattice wave vector.
