The function x< 0 0 < x < a ψ(x)-Ax(1-(x/a)] is an acceptable wavefunction for a particle in a one-dimensional space (x can take values between -oo and +oo) (a) Give two reasons why this is an acceptable wave function. (b) Calculate the normalization constant A. (c) Using the definition for the average of an observable "o" described by the operator "o": and to)
(C) An electron is described by the wavefunction (x) = 4 cos(2x/L) for the range = 5234 and is zero otherwise. (In other words, v(x) = 0 for 3 and 43 .) A useful integral is S cos?

(iii) Where is the maximum probability for...
A certain wavefunction is zero everywhere except between x = 0 and x = L, where it has the constant value A. Normalize the wavefunction.
A little blurry, but the wavefunction is a^(1/2)*e^-(ax/2). Not
sure how to find expectation value of the commutator. (What is the
commutator of this wavefunction?)
Ppie P7C. A particle is in a state described by the normalized wavefunction vex) ewhere a is a constant and 0 s xS oo, Evaluate the expectation value of the commutator of the position and momentum operators.
a) Find the potential V(x) associated with the wavefunction ψ(x) = Csech(ax) given that its energy eigenvalue is zero (i.e. E = 0). b) Plot V(x) and ψ(x) on the same graph.
What is the normalized form of the wavefunction x)Ax(L-x) for a one-dimension particle in a box with length L:
The wavefunction for an electron in the 1s orbital of a He+ atom is given by: ψ1,0,0 = (8 /πa03 )1/2 e -2r/a0 (1) Show that the wavefunction is normalized and calculate the expectation value for the radius explicitly. The following integral is helpful: R ∞ 0 = x n e −ax = n! a n+1
from the formula E(aX+b)=aE(x)+b, setting b = 0 we see that E(aX)= aE(X) Prove E(aX) = aE(x).
