can you explain further, inside a finite well, the wave function is either cosine or sine, so exactly what wave function are we considering around x=0 to decide parity if we dont even know what wave we are using at this point

If the Probability of each of the steps of the drunk man is equal (p = q = 1/2) obtain the Probability that act of 5 steps 3 of them would be to the right. . Calculate the relative width for random walk problem. if the total number of steps is N = 25 a. for equal number of steps to the right and left side (p = q) . b. for p = 0.4 , q = 0.6

4. a) Consider a square potential well which has an infinite barrier at x = 0 and a barrier of height U at x = L, as shown in the figure. For the case E L) that satisfy the appropriate boundary conditions at x = 0 and x = o. Put the appropriate conditions on x = L to find the allowed energies of the system. Are there conditions for which the solution is not possible? explain. U E L.
