Question

relation ship between energy and wave vector in the reciprocal space for free electron is ________________ options a)parabola b) hyperbola​

Answer 1

Answer:

i think it's a. parabola

Answer 2

The relationship between energy and wave vector in the reciprocal space for free electron is known as parabola.

• The vector of the wave is the inverse one and so is the number of waves per unit. It is a vector, because it is given the same direction as the propagation of the wave
• The relationship between energy and wave vector in the free electron reciprocal space is parabolic
• The electron movement in periodic potential depends on the electron's effective mass.
