Quantum Physics HELP

  1. May 23, 2009 #1
    Calculate the highest frequency X-rays produced by 8.00 · 104 ev electrons.

    2.0 x 10 19 HZ

    My teacher states it is wrong. This is on the final exam. I need help.

    How did you find your answer?

    that being said, you must use an equation relating Energy, frequency, and a constant. (same one as used with photons)

    Make sure you use consistent units - either eV or J.

    Simple equation. My answer is 1.93 x 10 Hz
