Homework Statement
In my study of Quantum Mechanics, I am using Introduction to Quantum Mechanics by David J. Griffiths. So far I have done quite well. However, as I come to the section on Angular Momentum, I need help to get further.
Homework Equations
Classically, the angular momentum of...
Homework Statement
To find the stationary states and the corresponding energies, I need to normalize the following equations:
X(x)=A_x sin(\frac{n_x\Pi}{a}x)
Y(y)=A_y sin(\frac{n_y\Pi}{a}y
Z(z)=A_z sin(\frac{n_z\Pi}{a}z
Because of their similiraty, these value of the normalize...
Homework Statement
My textbook indicates the following three important points are confirmed by Faraday's law of electolysis:
a) matter consists of molecules and molecules consist of atoms
b) charge is quantized; only integral numbers of charges are transfered to the electrodes
c)...

Homework Statement
Suppose a hydrogen atom is in the 2s stat, with its wav function given by:
\psi_2_s (r) = \frac{1}{4\sqrt(2\pi a_o^\frac{3}{2})} (2-\frac{r}{a_o}) e^(-\frac{r}{2a_o})
Taking r = a_o, calculate \psi_2_s (a_o)

Homework Statement
The ground state wave function for the electron in a hydrogen atom is:
\psi(r) = \frac{1}{\sqrt (\pi a_o^3)} e^\frac{-r}{a_o}
where r is the radial coordinate of the electron and a_o is the Bohr radius.
Show that the wave function as given is normalized...
