Certain devices utilize electromagnetic waves to determine the position and velocity of an object. In these devices, the waves are emitted, reflected off the object, and then returned to the device. By understanding the wave's speed and the time it takes for the wave to return, the distance traveled by the wave can be calculated. Which category of wave would be the most secure choice for such a device?

Answer 1

Opting for radio waves is the safest decision as they pose the least harm to organisms.

Radio waves are commonly used in various applications such as radar and communication and are known to be non-ionizing, meaning they do not have enough energy to remove tightly bound electrons, making them safer for biological tissues compared to other types of electromagnetic waves like X-rays or gamma rays, which can be harmful.
