Quick Summary

Grazing incidence refers to the phenomenon where X-rays strike a surface at a very small, glancing angle. This is distinct from the typical angle of incidence, which is measured relative to a line perpendicular to the surface.12

While X-rays are generally strongly absorbed by solid matter, they can be reflected by a metal surface when hitting it at grazing incidence. This property is crucial in X-ray optics, allowing for the focusing and reflection of X-rays, which is not possible with conventional optical methods used for visible light. The specific angle at which this reflection occurs is known as the grazing angle.34
