Question 9.10

Q 9.10: X-ray beam of wavelength undergoes a first order reflection from a crystal when its angle of incident to a crystal face is 26.5 degree, and an X-ray beam of wavelength 0.097nm undergoes a third order reflection when its angle of incidence to that face is 60 degree. Assuming that the two beams reflect from the same family of planes, calculate (a) the interplanar spacing of the planes and (b) wavelength.
