teaching electron diffraction

[elpida]

I'm doing my thesis and i have to teach electron diffraction to high school students. Can you propose to me any route to develop my teaching process, to be understood from high school students?

Develop the idea of diffraction for light, which is straightforward enough.

Then explain the basis for the de Broglie hypothesis. Show the experimental justification for the hypothesis -- students won't be willing to just accept it.

From there, you can logically develop the idea of electron diffraction.
