X-rays are a form of electromagnetic radiation often used in the medical field for diagnostic imaging. Since the waves can penetrate soft tissues in the body, but they are absorbed by denser materials such as bones, this allows medical professionals to take photographs of the internal structures of the body, such as the internal skeleton, helping to diagnose conditions or injuries.
The word is also often used to showcase the letter X when teaching the alphabet. The letter itself lamented that "X-ray" and "xylophone" are the only X-words that people know in Episode 3424 and Episode 3659 of Sesame Street.
