X-rays in a dental X-ray machine are produced when an electron converts its kinetic energy into a photon. In one particular X-ray machine, an electron accelerates through a potential difference of 9.00 x 104 V to create a single photon. What is the frequency of the X-ray produced in this particular X-ray machine?
