What is X-Ray ?
X-Rays are a from of electromagnetic radiation, as a is visible light, but with some different characteristics.
The important characteristic of X-Rays is that these can penetrate or pass through the human body but cannot pass through bones, hard items like bullets etc. This effect produces shadow-like images of structures such as bones, bullets etc. on a photographic plate. This helps to understand the inner details of body such as presence of foreign hard (bullets etc.) or any fracture in the bones.
