Can someone please explain the concept of how the diffraction pattern for x ray is the same for an electron and how does this support the wave - particle duality?
Thank you

Hey bts,
In the future post on the "Physics 3/4 thread" (Physics [3/4] Question Thread!)
This makes sure you'll get a response, and is easier for everyone else to see the question (when all the Year 12s are on the same page).
In regards to your question,
For diffraction patterns to be the same, the wavelength/w must be the same. Hence if the same w (atomic spacing for example) is used, wavelength MUST be the same as well.
Since electrons produce a diffraction pattern (which is a wave property) --> electrons (which are particles) are exhibiting wave like behaviour--> wave particle duality.
Hope that helps :)
Let me know if you need anything else!

thank you so much!
yes i will post in the question thread... sorry im new to this forum :)

No worries :)
