Radar works by sending out electromagnetic energy at a particular wavelength and receiving a reflected signal from distant objects, similar to a sound echo. Many modern military aircraft have what is known as “stealth technology” that allows the aircraft to be invisible to enemy radar. What statement best explains how this is possible? * 1 point A. The coating on the aircraft is highly reflective. B. The coating on the aircraft absorbs incoming light energy. C. The aircraft is extremely fast, allowing it to outrun the enemy radar. D. The aircraft has a very rounded shape that refracts incoming light energy.
