Which of the following is true about RADAR and LIDAR technology in terms of signal characteristics?

Radar and Lidar technologies indeed share the same fundamental wave properties because they both utilize electromagnetic waves for their operations. This commonality is foundational to how both systems detect and measure objects. RADAR (Radio Detection and Ranging) typically operates using radio waves, while LIDAR (Light Detection and Ranging) utilizes laser light, which falls within the optical spectrum.

By leveraging the principles of wave propagation, such as reflection, refraction, and scattering, both technologies can determine the distance, speed, and characteristics of objects based on the returned signals after they interact with surfaces. This shared reliance on wave properties ensures they can both effectively perform similar functions, despite differing in their specific applications and operational frequencies.

The other options do not accurately represent the shared characteristics of RADAR and LIDAR, as they do not operate at different speeds in a way that affects their wave properties, they have different wavelengths as one uses radio waves and the other uses light waves, and both technologies definitively utilize electromagnetic waves in their operation.
