Question

Bloch wave is a wave composed of a plane waves modulated by a
function
​

Answer 1

Answer:

A Bloch Wavecombines a plane wave with a periodic sequence of atomic orbitals. The amplitude of the atomic orbitals is modulated by the plane wave (shown dotted in the diagram below): uk(r) is a periodic function (for atomic orbitals) and exp[i (k r -wt)] a plane wave (forfree electrons).
