Hi, I need help with the following question. Could you pleaseshowyour work so that I may better understand how the solutionwasachieved? Thanks!
Upper plane d Lower planeUsethe figure as a reference for problems (1) and(2)
(1)Potassium iodide has a crystalline structure with atomicplanesseparated by 0.353 nm. A monochromatic x-ray shows afirst-orderdiffraction maximum when the grazing angle is7.60°.
a) Calculate the x-ray wavelength
b) Assume now that the x-ray is observed at an incident angleof31.9°. Will constructive interference occur? (Defend yourargumentcalculatively)
(2) Assume 0.140 nm x-rays are diffracted on aninterplanarspacing of NaCl, which is 0.281 nm.
a) What is the predicted angle in the first-order?
b) What is the predicted angle in the second-order?
c) What is the maximum order for reflection? Why?
