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

The safest choice for a device utilizing electromagnetic waves to determine the position and velocity of an object is:

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

Radio waves have low energy compared to other types of electromagnetic radiation, such as gamma rays or X-rays, making them less harmful to living organisms. They are commonly used in various applications, including radar and telecommunications, due to their safety and effectiveness for distance measurement.
