Question

What is the de Broglie wavelength of electrons with the following value of kinetic energy? 1.06 keV.

Answer 1

I heard you the first time.

De Broglie wavelength is h/(momentum)

h is Planck's cnstant

Use the Kinetic Energy of the electron (E) to get the momentum.
Momentum = sqrt(2E*m)

The energy E will have to be in Joules. I trust you know how to make that conversion.
