How does LIDAR differ from RADAR in terms of the type of waves used?

• A. LIDAR uses radio waves while RADAR uses light waves
• B. LIDAR uses sound waves while RADAR uses laser beams
• C. LIDAR uses light waves while RADAR uses radio waves
• D. LIDAR uses electromagnetic waves while RADAR uses thermal waves

Answer: (C)

LIDAR technology relies on light waves, specifically in the ultraviolet, visible, or near-infrared spectrum, to measure distances and create detailed images of the environment. This use of light allows LIDAR to achieve high resolution and precision in mapping and detecting objects. In contrast, RADAR utilizes radio waves, which are longer in wavelength compared to the light waves used by LIDAR. This fundamental difference in the type of waves directly affects the applications and effectiveness of each technology. While RADAR works well for detecting larger objects at long distances, LIDAR excels in applications requiring fine detail, such as topographical mapping and vegetation analysis.
