Homework Statement
A cubic crystal has a spacing between atoms of d = 0.2 nm. What is the minimum energy for X-rays such that non-trivial Bragg reflection may occur (peak with n =1)?
Write your answer in units of keV.
Homework Equations
2dsinθ = nλ
The Attempt at a Solution
i have no idea what I am doing. i don't remember the instructor talking about this nor can i find lecture notes on bragg reflection.
the only reason i know the "relevant equation" is because of a class i took semester where we did an experiment to show bragg reflection.
any advice would be appreciated. the second question is similar to this one.
