X-rays are usually produced by making high-velocity electrons collide with metallic targets. For electrons accelerated in a field of 75,000 volts,a. compute the wavelength (in nm) of the x-rays producedb. if this same kinetic energy is transferred to a proton, how fast would the proton be traveling (in m/s)?

- Needs Complete solution with 100 % accuracy. Don't use chat gpt or ai i definitely upvote you.arrow_forwardI am struggling with getting this question done and need some help solving it, explain and make sure the answer is 100% correct. When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced; the electron slows down. In the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy Eγ�� of a photon of radiated light: Eγ=K−K′��=�−�′, where K� and K′�′ are the kinetic energies of the electron before and after radiation, respectively. This kind of radiation is called bremsstrahlung radiation, which in German means "braking radiation" or "deceleration radiation." The highest energy of a radiated photon corresponds to the moment when the electron is completely stopped. Part A.
