Answer 2

ＡＮＳＷＥＲ :

Ｅffective mass is that mass which an electron seems to have when it is present in the periodic potential in a lattice crystal.

POINTS TO BE REMEMBERED:

• NATURE the graph between the energy and the propagation constant (k) is in the parabolic form.

• electrons or electron holes in a solid, the effective mass is usually stated in units of the rest mass of an electron, me (9.11×10−31 kg).
