Final answer:
The question asks to sketch the directions within a cubic unit cell represented by Miller indices enclosed in square brackets. The directions are given for each specified Miller index.
Step-by-step explanation:
The directions within a cubic unit cell can be represented by Miller indices enclosed in square brackets. The Miller indices represent the direction of the vector within the unit cell.
- [101]: This direction passes through the midpoints of opposite edges of the cube.
- [211]: This direction passes through the corner of the cube and bisects the edge along one face.
- [102]: This direction passes through the corner of the cube and bisects the edge along one edge.
- [313]: This direction passes through the corner of the cube and bisects the edge diagonally.
- [001]: This direction passes through the center of opposite faces of the cube.
- [212]: This direction passes through the corner of the cube and bisects the edge along one face.
- [312]: This direction passes through the corner of the cube and bisects the edge diagonally.
- [301]: This direction passes through the corner of the cube and bisects the edge along one face.
