Right, probability is not supposed to change with time for stationary states, and it doesn't matter if it's 3 seconds or 0 seconds.
So to calculate the probability, I can use the sin wavefunction, and I suppose the initial wavefunction must then be used in the second part, since the expectation...
I apologize in advance for not being familiar with LaTex.
1. Homework Statement
One thousand neutrons are in an infinite square well, with walls x=0 and x=L. The state of the particle at t=0 is :
ψ(x,0)=Ax(x-L)
How many particles are in the interval (0,L/2) at t=3?
How many particles have...
Dear BvU,
I am fortunate enough to have solved it. I thank you for being willing to help. (: The professor solved it in class and it indeed involves some trigonometry.
Homework Statement
Show that the S' axes, x' and ct', are nonorthogonal in a spacetime diagram. Assume that t = t' = 0 when x = x' = 0. (Hint: use the fact that the ct' axis is the world line of the origin of S' to show that the ct' axis is inclined with respect to the ct' axis. Next, note...
