1. Homework Statement

X-rays of 1.54 angstroms are reflected off copper powder

Find the cubic lattice and the length of an edge of the unit cell.

2. Homework Equations

nλ = 2d sin(Θ) ; the Bragg equation

3. The Attempt at a Solution

The cubic latice is face centered at d110? Because it has 5 planes of reflection?

I tried plotting sin(Θ) vs. n to get the slope and calculate a, but it doesn't seem right?

How do I find the length of an edge of the unit cell and what is the cubic lattice?
