- Copper Kα1X-rays have a wavelength of 0.15406 nm. What is the interplanar spacing d, for the (200) planes in iron when the Bragg angle θ is 32.52 ̊ (assuming n=1, first-order diffraction)?In June 1985, a laser beam was sent out from the Air Force Optical Station on Maui, Hawaii, and reflected back from the shuttle Discovery as it sped by, 354 km overhead. The diameter of the central maximum of the beam at the shuttle position was said to be 9.1 m, and the beam wavelength was 550 nm. What is the effective diameter of the laser aperture at the Maui ground station? (Hint: A laser beam spreads only because of diffraction; assume a circular exit aperture. A. 0.232 m B. 0.199 m c. 0.047 m D. 0.052 m
