##### Reference no: EM13542606

Monochromatic x rays are incident on a crystal for which the spacing of the atomic planes is 0.442 . The first-order maximum in the Bragg reflection occurs when the incident and reflected x rays make an angle of 39.6 with the crystal planes.

Part A: What is the wavelength of the x rays?
