Quantum Physics: Calculate Highest X-Ray Freq of 8.00E+04 eV Electrons

[miley06]

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
