Question

I'm having a hard time with their hand writting. Please copy what is written down on this paper into easily readable text. (If it helps, the topic that they're talking about is physics, superconductors.) Try to do as much as you can.

Explanation / Answer

1.

Bragg's law --> 2 d sin ? = n ?

For order 1st  order diffraction n = 1

Therefore, ? = 2d sin ?

Using the above equation one can determine crystal structure.

X-ray diffraction measurement can be done using powder of crystalline material.

Using above method one can determine (hkl) plane of crystal.

From the diffraction pattern obtained from the X-ray diffraction one can distinguish crystalline phase as well as determine crystal structure.
