I have an electron that I want to put in a rigid box. How small do I need to make the box so that the speed of my electron in its ground state inside the box will equal to the speed of light?
NO NEED TO SOLVE SINCE CORRECT ANSWER IS 1.2 PM
SKETCH THE U(X) AND Ψ(X)
Solve the “particle in a box” problem to find Ψ(x, t) if Ψ(x, 0) = 1 on (0, π). What is En? The function of interest here which you should plot is |Ψ(x, t)|2.
Consider a 1-dimensional quantum system of one particle
Question 01:
in which the particle is under a potential V(x) = mw?a?, with m being the
mass of the particle and w being a parameter (you may take it as angular fre-
quency) with inverse dimension of time. The particle may be found in the region
-0 < x < o.
Varify that the lowest two states of the system are mutually orthonormal.
