Radio Frequency Energy is transmitted by a radar. When it strikes an object, what is reflected back to the radar's receiver and presented visually on a scope?

Explanation:
When the radar sends out RF pulses, some energy bounces off objects and returns toward the radar. This returned energy is the echo. The receiver captures the echo, and the display on the scope shows it as a blip whose position indicates range (based on how long the round trip took) and whose brightness relates to how strongly the object reflected the signal. Light and random noise aren’t what the radar displays for a real target; the visual cue on the scope is the echo of the transmitted energy.
