Ok. We were told that one side of a unit cell of any of the crystals was 2d so we calculated the volume of a unit cell from that (2d)^3. Then we calculated the mass of a unit cell by using the fact that there are 4 atoms of each of the 2 elements in 1 unit cell and by calculating the mass of one...

Hi, In our lab session on x-ray crystallography we found values for d, the plane separation using Bragg's law and from that we are supposed to find the density of the crystals (Lithium Fluoride, Rubidium Chloride and Potassium Chloride). However, when we calculated the densities they were...

I am in my second year of an undergrad degree in physics and we have to write a 2000-3000 word essay on a topic of our choice. This can be any aspect of physics or anything related to physics with sufficient physics content and should be written in a popular science style. My problem is I...
