Final answer:
True. The information that is being sensed is indeed the reflection of electromagnetic (EM) energy off a target.
Step-by-step explanation:
True. The information that is being sensed is indeed the reflection of electromagnetic (EM) energy off a target. Electromagnetic radiation is generated by a moving electric charge, such as an electric current. When the current oscillates, an EM wave is propagated, and this wave can be reflected off a target and sensed.
