Like the revolving mirrored ball that reflects a spotlight on a dance floor,a crystal of beryl fragments a beam of x-rays. The narrow beam was projected through the beryl,and the black spots reflect the regular lattice of atoms within the crystal. This technique of x-ray diffraction is used to work out the atomic structure of different elements. A similar technique was used to decode the double-helix spiral of DNA molecules | |
