The term "X-ray" was coined by Wilhelm Röntgen in 1895, who discovered the radiation. He named it "X" to signify its unknown nature (as "X" often represents an unknown variable in mathematics) and "ray" for its beam-like properties. Over time, "X-ray" became standardized in scientific and medical vocabulary, retaining its original spelling and symbolic meaning.
