    Physics degree in India after BE?

    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...

    Graduate Understanding WKB Approximation for E-V(x)

    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...

    Graduate Why did we need a 8.3 T magnetic field in the LHC beam pipe?

    Thank you so much!

    Graduate Why did we need a 8.3 T magnetic field in the LHC beam pipe?

    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?

    Graduate Why did we need a 8.3 T magnetic field in the LHC beam pipe?

    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...

    What Should a New Member Expect on Physics Forums?

    Hi, I just joined PF. I hope to learn new things (it would be great if I could eventually help others too). :)
