can i get a clear well explained answer, dont repost the answer because i didnt understand it

thanks

(a) Consider a tetragonal unit cell with lattice parameters: a=b=5.2Ac=10.14A Draw a perspective representation of the unit cell and label the axes, the angles, and the origin. Digitally generated drawings will not be marked. [4 marks] (b) Redrawing the unit cell in (a) for each case, sketch the following planes: (133),(101),(050) Show your work in determining points of intersection with the unit cell axes. A single plane for each set of indices is sufficient. Digitally generated drawings will not be marked. [ 6 marks] (c) Redrawing the unit cell in (a) for each case, draw the following directions: [211],[101] Digitally generated drawings will not be marked. [4 marks] (d) Calculate the interplanar spacings (d-spacings) and the angles expected in an X ray diffraction pattern (2) for the planes in (b). Take the X-ray wavelength as = 1.5406 A. Show your work. [6 marks]
