WebUsing an X-ray spectrometer, he measured the wavelength of X rays scattered from light elements. In addition to scattered X rays that had the same wavelength as the primary beam, he found a second, or "modified," peak at a longer wavelength. The intensity and wavelength of this second peak were functions of the scattering angle from the sample. WebA parallel grid may cause "grid cut off" around the edges of the film, since x-ray photons at the perimeter of the primary beam may be absorbed by the lead strips. A focussed grid possesses gradually sloping strips on either side to allow for the divergence of the primary beam, therefore helping to avoid grid cut off.
