During which conflict was infrared first used?

• A. WWI
• B. WWII
• C. Korean War
• D. Gulf War

Answer: (B)

Infrared sensing uses the heat that objects emit to “see” in the dark. The first military use of this idea appeared in the 1940s during World War II, when researchers and armed forces began experimenting with heat-detecting devices to locate aircraft and other heat sources at night. These early systems showed that you could detect a heat signature even without light, marking the initial adoption of infrared in warfare. Later conflicts like the Korean and Gulf Wars benefited from much more advanced thermal-imaging capabilities, but the very first use happened in World War II.
