X-rays of wavelength 0.13 nm fall on a microcrystalline powder sample. the sample is located 17 cm from the photographic film. the crystal structure of the sample has an atomic spacing of 0.22 nm. calculate the radii of the diffraction rings corresponding to first-and-second-order scattering. note in the figure 35-28 in the textbook that the x-ray beam is deflected through an angle 2pi. express your answer using two significant figures. enter your answers numerically separated by a comma.
