Bragg's Equation Problem X-rays of wavelength .0960nm are diffracted by a metallic crystal, angle of first order (n=1), is measured to be 17.8. What is the distance (in pm) between the layers of atoms responsible for diffraction? I do this: 96pm / 2sin17.8 and I keep getting ~173.9pm The answer is supposed to be 157pm. What am I doing wrong?
