Problem 8: An X-ray beam of wavelength 0.48 × 10-10 is used to get Brag reflection from a crystal at an angle of 20o for the first order maxima. What are the possible layer spacing which gives rise to this maxima?
Solution
Given data
Wavelength used =λ = 0.48 × 10-10 m, Angle of incidence = 20o
Order of fringe (maxima) = 1
