 P: 28 I am a beginner to quantum mechanics and am trying to make sense of Schrodinger's Equation. I am attempting to find probabilities in the case of a free particle in the general case. It is my understanding that the solution to Schrodinger's Equation in the general case of a free particle is as follows: $$\psi(X,T) = e^{i/\hslash ( px - Et)}$$ The modulus square of this is 1, which means the probability density function is uniform. Two questions: 1. Over what values of x is this pdf defined? Can we eliminate all values of x > ct? 2. Am I correct to interpret x as the distance from the (known) starting position of the particle at t = 0? Thanks.
