HW9
1. Demonstrate that the wavefunction of a free particle with mass solves the time dependent Schrödinger equation (3 points). Is the complex number i in both the Schrödinger equation and that wavefunction crucial to the conservation of total energy for a free particle with mass m (1 point)? In other words, what fundamental physical statement is connected whenever a complex wavefunction solves the Schrödinger equation? (1 point)
2.
Demonstrate that the wavefunction of a free particle without mass, e.g. photon,
solves the time dependent wave equation (which is in
