In what year was RADAR developed for military use?

• A. 1935
• B. 1947
• C. 1946
• D. 1886

Answer: (A)

RADAR, which stands for Radio Detection and Ranging, was first developed for military use in the 1930s. The year 1935 is significant because it marks one of the first practical applications of RADAR technology by the British military. The technology was initially used to detect aircraft by sending out radio waves and analyzing the echoes that returned, allowing for early warning and improved defensive capabilities. This foundational development paved the way for advancements in both military and civilian applications of RADAR technology throughout the following decades. The other years provided do not align with the initial military development of RADAR. While 1946 and 1947 are post-World War II years when RADAR technology had advanced, they do not represent the origin of its military application. The year 1886 corresponds with an entirely different context, related to electromagnetic radiation and telecommunications, rather than RADAR technology as we know it.
