Question
In his original paper, de Broglie suggested that E = hv and p = h/λ, which hold for electromagnetic waves, are also valid for moving particles. Use these relationships to show that the group velocity ug of a de Broglie wave group is given by dE/dp, and with the help of Eq. (1.24), verify that vg = v for a particle of velocity v.
