Problem Set #2
1. (25 points) You might think that the [ hkl ] is perpendicular to the plane ( hkl ) .
However, this is not always the case. Show that the [ hkl ] direction is only perpendicular
to the ( hkl ) plane f

I feel like I am getting a real-life experience of the "Uncertainty" in Quantum. This morning, I
was half-asleep and thought we had a lab today, so I got up and answered the prefab
