X rays are also called which of the following?

X rays are also called which of the following?

• A. Radioactive rays
• B. Gamma rays
• C. Roentgen Rays
• D. Infrared radiation

Answer: (C)

X rays were discovered by Wilhelm Roentgen, so they were historically referred to as Roentgen rays in his honor. This naming reflects the origin of the discovery and persisted in many older texts and clinical references. The modern term is X-rays, but when asked what X rays are also called, Roentgen rays is the best answer because it directly ties to the discoverer’s name. Gamma rays come from nuclear transitions and are a different type of high-energy radiation, infrared radiation is far lower in energy and belongs to a different part of the spectrum, so neither fits as the traditional label for X-ray radiation.
