Question

heeeelp , best answer will get the points right away


What experimental technique requires the use of crystal structure notation (directions and planes, especially)? What is this technique used for? This was covered lecture. Sketch the unit cell of a bcc meat (which has an atom placed at each lattice point) and shade in the (010) plane. Draw just one unit cell. This plane intersects the centers of how many atoms in one unit cell? Repeat part (a) expect use the (020) plane. Again, just one unit cell. In a cubic unit cell, sketch a [111] and a [112] lattice direction. Use trigonometry to calculate the angle between these two directions.

Explanation / Answer

A. the experimental technique is known as X-ray cristallography. and it is used to determine crystal structures of metals.
