This and the idea of coherence were my concern...real and complex numbers come along the calculation,but that is not what I am really worried about....
I think I could not convey the question to you.
Physicsmonkey,complex numbers are needed when we are thinking about something imaginary.\vec{E} and \vec{B} field in EM theory are real...
Precisely.The descriptions are quite similar.In the case of classical optics, the primary wave is present at the two slits,simultaneously.In QM, a...
Alphaneumeric,I did not opened that blog to help you,one who knows everything and discourage elementary physics discussions.And I do not feel ashamed...
I want a clarification in the idea of superposition principle.Perhaps,I should rather say that the distinction of superposition principle in QM and...
Yes...thank you for your help...In the mean time,I tried with the suggestion of rasmhop in physicsforums;but that reduced to this case only,as it...
OK,now I think I see the crux of the matter: whatever the indefinite integral is,the resulting form will be \ [\ f(\ t,\ x)\ ]_{\ t\ =0}^{t\ =\ ln\...
Hello friends,I could not be online last night;so apologies for not sending a reply. Yes,I made a typo in the sign of the exponential. But I...
I have to evaluate the numerical value of the derivative of the following integral for x=1 \int_{0}^{\ ln\ x}\ e^{\ -\ x\ (\ t^2\ -\ 2)}\ dt...
The idea is of a classical atom.Since, the atoms were to have internal structure (evident from excitation spectrum experiments),people thought of...
Following the ideas of physicsmonkey,in those days,it was usual thought that materials will have some memory.Chemistry was a superficial subject...
@physicsmonkey,I see what you mean...I will think about it and will write later... @ scifes,you are absolutely correct...but here we are talking...
Hi friends, Can you help me to seeing the meaning of the following pat from Gottfried's book on qm?to illustrate the failure of classical physics...
Yea...for an operator \ T_\ a,which shifts by a constant distance a, \psi\ (\ x)\rightarrow\psi\ (\ x-\ a) Even though the two transformations...
The scenario is clearer if the following viewpoint is taken: You take the wavefunction \psi.Give some spatial translation to \psi,w.r.t. the...
In Franz Schwabl's QM book the idea of active transformation has been put in this way: "transformation of a state Z to Z' and view Z' from the same...
ya...that's what I found...I was confusing with something else....
My question was if the result will hold good for the case where D1 and D2 do not commute (in the sense of matrix multiplication).Say,[D1,D2]=cD3...
The following limit result is well known: e^x = \lim_{n\to \infty} \left(1 + x/n \right) ^n Now,with matrix valued argument,the above equation...
