Question

A non-relativistic electron in free space has velocity of 105 m/s. If its wave is described by a packet, and at t=0s the packet amplitude a(k) = 1 with width Δk centered at ko.

a. Calculate its wavelength.


b. Write an equation that would allow us to calculate the wave equation from the known shape of a(k), and sketch the resulting wave Ψ(x,0).
