Since you have declared an interest in being a physicist, I am assuming that you are in it for the long haul and plan to complete your PhD, postdoctoral studies, etc. I would suggest that you appear for entrance exams that will allow you entry into integrated MSc-PhD programmes. You could sit...
Consider E>V(x). WKB states the wavefunction will remain sinusoidal with a slow variation of wavelength $ \lambda $ and amplitude given that V(x) varies slowly. From the equation \begin{equation}
k(x)=\frac{\sqrt{2m(E-V(x))}}{\hbar}
\end{equation}, I can see that the k(x) is directly...
Thank you so much for your reply. :) Actually, I was wondering more along the lines of why 8.3, it seems like a weird number. Is there some calculation after which we arrive at this figure?
I tried to work backwards and verify the magnetic field required by the LHC beam pipes. A circumference of 27km implies a radius R=4300 m. The beam energy E is 7 TeV per proton beam. Considering approximation E approximately equal to pc to get momentum (ultra-relativistic case). Plugging into...
