What is a typical use of X-rays as summarized by Quentin?

• A. music broadcasts
• B. luggage inspections
• C. night-vision goggles
• D. digital photographs

Answer: (B)

X-rays are commonly used for luggage inspections in security settings, such as at airports. This application leverages the ability of X-rays to penetrate various materials, allowing security personnel to see the contents of bags without opening them. The X-rays generate images that highlight the differences in density between various objects, helping to identify potentially dangerous items or contraband hidden within luggage. This method of inspection is rapid and efficient, making it a standard practice in ensuring safety during travel. The other options listed do not utilize X-rays for their function; for example, music broadcasts deal with sound waves rather than electromagnetic radiation, and night-vision goggles primarily rely on infrared technology. Digital photographs are formed through capturing visible light, not X-rays.
