OK. I think I worked it out. The key is to remember that Braggs law is nl = 2d sin(T) NOT l = 2d sin(T) where n is diffraction order, l is wavelength, d is plane spacing and T is angle of diffraction. If d = a/sqrt(h^2 + k^2 + l^2) then Braggs law is
nl = 2*a/sqrt(h^2 + k^2 + l^2)*sin(T)...
I'm trying to get my head around indexing x-ray diffraction patterns and this thought experiment stumps me. Let's say I have a crystal with a simple cubic lattice structure:

I align a narrow x-ray beam incident on the crystal so that the x-ray...
Unfortunately all information is contained in the question. This question is taken directly from chapter 1 problem 2 of Classical Mechanics by Kibble and Berkshire. I'm not sure if this is a good book yet or not. From your reply it seems the question does not contain enough information to find...
[b]1. The two components of a double star are observed to move in circles of radii r_1 and r_2. What is the ratio of their masses? (Hint: Write down their accelerations in terms of the angular velocity of rotation, w)
The answer is m1/m2 = r2/r1.
How does one cancel the velocity from the...
