Use the uncertainty relation to find an estimate of the ground state energy of the
harmonic oscillator. The energy of the harmonic oscillator is
.
Problem 2:
The wave function of a particle at t=0 is
.
At t=0, what possible values of the momentum of the particle
can be found, and with what probability?
Problem 3:
Electrons of kinetic energy 10 eV travel a distance of 2 km. If the size of the initial
wave packet is 10-9 m, estimate the size at the and of their travel.
