Question

When you receive a chest x-ray at a hospital, the x-rays pass through a set of parallel ribs in your chest. Do your ribs act as a diffraction grating for x-rays?.

Answer 1

Because the wavelength of photons with the significance of order 10 KeV is a little smaller than the spacing of particles in solids, a crystal will act as a sort of diffraction grating for an x-ray. As a crystal is three-dimensional, the diffraction requirements are more stringent than for a two-dimensional grating.

What is x-rays?

• X-rays use invisible electromagnetic power beams to assemble images of internal tissues, bones, and organs on film or digital media. Standard X-rays are conducted for many reasons, including analyzing tumors or bone injuries.

• X-rays can be utilized to examine most regions of the body. They're especially used to look at the bones and joints, although they're sometimes used to detect difficulties affecting soft tissue, such as internal organs. Situations that may be detected during an X-ray include bone fractures and breaks.

• The wavelength of X− rays are very small (≈A). Hence they are not diffracted using standard grating.
