Sketch within a cubic unit cell the given direction and plane. The origin point for the index of direction is 0, 0, 0. [112] and (oīī) -

A unit cell has a=5Å, b=5Å, c-8Å, a=90°, B-90° ad y=90°. What will be the Bravais lattice for this unit cell? Mention the following for each of the given crystallographic cubic planes. (a) Intercepts in the x, y and z coordinates (b) Reciprocals (c) Final index of the crystal plane 1/2

(a) Mark the sites in the unit cell. b (b) List the Miller indices of all the octahedral interstitial sites in the FCC unit cell.

In a certain unit cell, planes cut through the crystal axes at (2a, 3b, c), (a, b, c), (6a, 3b, 3c), (2a, -3b, -3c). Identify the Miller indices of the planes.

3.60 (a) What are the direction indices for a vec- 231 in a 342 11 tor that passes from point 10 to point 32 tetragonal unit cell? (b) Repeat part (a) for a rhombohedral unit cell.

Please explain me this problems! Please don't reject this!! this is just HW problems.  I waited the solutions for more than 4 hours, but you guys just reject all the questions.. please..
