1. Each of following figures is a unit cell with a right-handed coordinate system: All intercepts are simple fractions of a lattice parameter. Write the indices for each point, direction or plane in the corresponding answer box. Label the origin with O if it is not indicated. Use correct notation .

2. Draw the following in the unit cells provided. (First decide: is it a point, direction or plane?) (2 0 1) b. / 5 / 5 / 5 a. [ 1 2 3] Divide by 3, shift origin (this arrow is difficult to draw on the computer: from tail move -1/3a, +2/3b, -c 1/2 1/2 1 c. Move origin to corner indicated by either small arrow. invert: ½ infinity -1 are the axial intercepts. 1/2 1 1/2 b. [ 2 3 1] Move origin to corner indicated by small arrow. Divide by 3: -2/3 1 -1/3 That’s the coordinate for the head of the direction vector.
