Sorry if this is the wrong forum.

There is a cathode and an anode and one is emmiting an electron (whichever one of the two does that, I honestly forget)

The electron moves through a electric potentinal of 70,000 volts. When it reaches the other side an Xray photon is emitted.

1) What is the maximum frequency of the XRay wave.

and how is that derived

I wont be giving you any more hints as you have not shown any effort nor have you stated what you know.

Find the energy of the electron.
