6. The Particle in a Box problem refers to a potential energy function called the infinite square well, aka the box: ; x < 0 (Region I) V(x) = 0 : 0 L (Region II) x x >L (Region III) Let's investigate a quantum particle with mass m and energy E in this potential well of length L We were unable to transcribe this image6d (continued) write down an equation relating ψ, (x = 0) to ψ"(x I and II....
An electron in a one-dimensional infinite potential well of width L is found to have the normalized wave function ψ(x)- sin(2 r ). (a) What is the probability of finding the electron within the interval from x=010 x = L/2 ? (b) At what position or positions is the electron most likely to be found? In other words, find the value(s) of x where the probability of finding the particle is the greatest?
Exercise 10.14 A particle is initially in its ground state in an infinite one-dimensional potential box with sides at x = 0 and x a. If the wall of the box at x-a is suddenly moved to x = 10a, calculate the probability of finding the particle in (a) the fourth excited (n = 5) state of the new box and (b) the ninth (n 10) excited state of the new box.

Which of the following are acceptable wavefunctions for a particle in a one-dimensional box? Check all that apply. ψ(x) = C(1 - sin(nπx/a)) ψ(x) = Acos(nπx/a) + Bsin(nπx/a) ψ(x) = E/cos(nπx/a)ψ(x) = D(a - x)xψ(x) = Cx3(x-a)
When we discussed the particle in a box model, we defined our box to be from x=0 to x=a. Re- examine this problem, defining the box to be from -a to +a. Recall that the general solution for a particle in a region of V=0 is ψ = A sin kx + B cos kx. Apply the appropriate boundary conditions, figure out what k is (in terms of a), and normalize your solution (i.e. evaluate A and B). .
