What is an x-ray?

An x-ray is defined as an invisible wave packet of energy known as a photon. This type of electromagnetic radiation has a unique ability to penetrate matter, particularly biological tissues, which is crucial in medical imaging. The energy of x-rays allows them to pass through the body and expose a photographic film or digital sensor, creating images of the internal structure.

This property makes x-rays particularly valuable for diagnosing conditions, as they can reveal details about bones, teeth, and other internal organs. Unlike visible light, which our eyes can perceive, x-rays are not visible to the human eye, necessitating special equipment to capture images. Thus, understanding x-rays as photons highlights their distinct nature and usefulness in medical and dental practices.
