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