X-rays are a form of high-energy electromagnetic radiation. X-rays tend to pass through materials composed of atoms with relatively little mass. Examples of such materials include air, water, and soft tissue. In contrast, X-rays tend to be absorbed by materials such as metal and bone, which are composed of atoms with greater mass. One use of X-rays is to diagnose problems with bones and teeth. Which is most likely to be another application of X-rays?
