An x-ray tube with a copper target is operated at a potential difference of 25 KV. The glancing angle (θ in our discussion of Bragg scattering) for first order constructive interference with a NaCl crystal for the Cu Kα line is found to be 15.8o. The planar spacing of NaClis 0.282 nm.

Find the wavelength of that Kα line.

Find the short wavelength limit for this x-ray tube? (Hint: Recall the mechanism of the inverse photoelectric effect and theresulting

Duane-Hunt rule for x-ray tubes.) Find the first order glancing angle (θ) for photons at the short wavelength limit.
