Need help with "X-ray production" Hi everyone. i am in 12th grade now. im having problems with the production of X-ray... Can someone tell me how X-ray is generated? From the very begining...to the charateristic raditaoin and the Bremsstrahlung Radiation...to the intensity graph (the one with two peaks). I don't understand why the graph is like that...i mean, what is the relationship between wavelength and x-ray intensity? I also don't get the calculation: when do we use qV=1/2 mv^2, and when do we use qV=hf? (q is the charge of electrons, V is the potential difference, 1/2mv^2 is the kinetic energy, h is plank's constant, f is frequency.) And how can we find out the followings if only an x-ray intensity graph is given? 1. the potential difference 2. the difference of energy between the ground state and the first excited state? And...if a rough x-ray graph is given...what will the new graph be when the potential difference is half? I'm going to take the IB physics exam soon in May(similar to AP in US, A-level in UK) and i still dont get this X-ray stuff. Can somebody help me? thanks a lot!
