Hi all. finished the first two papers from my final degrees in physics. Paper 1 was fine but paper 2 was just horrible . I attempted 3/4 q's not all greatly, My question is: Has anyone else here left an exam feeling rotten about what they answered and after a few results showed you didnt too...

but does the peak have any use for the calculation. suppos it was the 422 peak

need help working out this problem. if you have a simple cubic lattice characterised using x-ray diffraction with a wavelegth of 1.6\dot{A}. The main peak in the scan is (222) and the angle is 32 degrees. By using braggs law to find the lattice constant do you just sub in the values and solve...

Hi, I am having a lot of trouble with 2 questions for my physics class.Waves and sound are my weakest points and always struggle to complete a full question the first one is: 1)Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern...
