The cool thing with Physicists is that they don't solve random problems blindly, just for the fun of mathematical exercise. All sort of mathematics could be done with discontinuous functions. However, Physicists define the wave function as a quantity that describes the probability to find a...
Hi there,
Was also looking for information on spatial hole burning. I how ever see a little rapport between the two explanations you provided.
In the first, the gain medium is linear and the waves traveling in opposite directions superpose to form standing waves. This causes depletion of the...
Oh, that's true.
In this case, what condition should we place on the statement i did mention above?
i.e if A and B commute, then any eigenket of A is an eigenket of B.
I know that when two operators A and B commute, any eigenket of A is also an eigenket of B.
As such, i think(Not certain though) that it suffices in this case to find eigenkets of either A or B and then normalize the vectors. What do you guys think?
Thanks to all for your help. I am actually grabbing some sense out of your comments.
My problem still remains.
Let's consider for instance an Adiabatic expansion of an ideal gas. We have the first law:
\DeltaU = Q - W.
Now Adiabatic process \Rightarrow Q = 0, hence
\DeltaU = - W.
But W...
Hi,
The first law of thermodynamic is sometimes written as
\DeltaU = \DeltaQ-P \DeltaV and sometimes as \DeltaU = Q+W, and sometimes \DeltaU = Q - W. I am confused about all these.
I also know that W is positive when the system in question does work to its surrounding and negative...
