SUMMARY
The discussion centers on the relationship between Copper's X-ray wavelength of 1.54 Angstroms and the calculation of the interplanar distance in Aluminum using Bragg's Law. The Bragg angle for reflection from the (111) planes in Aluminum is given as 19.2 degrees. By applying the equation nλ = 2dsinθ, where n is the order of reflection, λ is the wavelength, d is the interplanar distance, and θ is the Bragg angle, participants clarify how to compute the interplanar distance for Aluminum's fcc structure based on the provided parameters.
