Weeks 2, 3, 4 Assignment: The Quantum World Question #13

[Areana V-M 1B]

I'm going back to my old achieve assignments and I got the second part wrong for Eelectron. I found the energy of Ephoton but I was having trouble for the Eelectron. Can someone explain to the process of finding the electron and any tips or advice.

This question requires equations from the equations and constants sheet. It uses both the equation for kinetic energy and the equation for electron wavelength. First solve for mv in the kinetic energy equation, then substitute that as the momentum p in p/h for wavelength. Make sure that your units are converted. It is important to be able to use and manipulate these equations for application questions such as these.
