An X-ray tube has an applied voltage of 68 kV. What is the most energetic x-ray photon it can produce? Give your answer in 10-14 J.

A color television tube also generates some X-rays when its electron beam strikes the screen. What is the shortest wavelength of these X-rays in picometers, if a 33.9 kV potential is used to accelerate the electrons? (Note that TVs have shielding to prevent these x rays from exposing viewers.)

What is the energy in eV of the n = 1 state for an atom with 1 protons? Assume the ground state energy for hydrogen is -13.6 eV.

If a hydrogen atom has its electron in the n = 6 state, how much energy in eV is needed to ionize it?

X-rays are produced when the electron stream in an x-ray tube knocks an electron out of a low-lying shell of an atom in the target, and an electron from a higher shell falls into the lower-lying shell. The x-ray is the photon given off as the electron falls into the lower shell. The most intense x-rays produced with a copper target have wavelenghts of 1.542A and 1.392A. These x-rays are produced when an electron from the L or M shell...
