Electrons are accelerated through a potential V and then they are suddenly stopped and emit photons. Derive the minimal value that the potential should have in order to produce some X-Ray photons of wavelength 10-10m.
The Attempt at a Solution
I used E=hc/λ to find the energy of the X ray photons. I found E= 1.989x10-15 = 12431.25 eV
Not sure if I needed to do this or what to do next. All help is appreciated. Thank you.
