Question

X-rays of wavelength 0.1 amstrong are reflected from the plane of inter planar spacing 2 armstrong .Calculate the glancing angle corresponding to second order reflection

Answer 1

The spacing of one set of crystal planes in NaCl (table salt) is d = 0.282 nm. A monochromatic beam of X-rays produces a Bragg maximum when its glancing angle with these ... Assuming that this is a first order maximum (n = 1), find ... X-ray. The wavelength of an X-ray is of order 1 Å = 0.1 nm which corresponds
