Question

1. Determine if the plane (113) is parallel to the following directions: [100], [224], 1211]. and [TTo] . 10] 2. For cubic lattice, calculate inter-planar distances between (122) plains and (113) planes. At what angle these planes cross each other. 3. For Si lattice, identify all the planes comprising at least three of the highlighted atoms:
