Beam Base Reviews
How do I find the wavelength of X-ray beam on the basis of interatomic distance and the angle of maximum reflection?
An X-ray beam of unknown wavelength is diffracted by a surface of NaCl. If the distance between the crystal is 285 hours and the maximum reflection angle is 7.21 degrees, which is the wavelength of X-ray beam? Suppose n = 1. I no clue here. Any help is appreciated.
2dsin (theta) = nx wavelength = wavelength (2dsin (theta)) Length Wave / n = (2 x 285 x 10 ^ -12 x sin (7.21)) / 1 wavelength = 2 x 285 x 10 ^ -12 = 7.15 x 0.1255 x 10 wavelength ^-11m
