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?

Choosing ultraviolet waves is the safest option since they are the most visually detectable.

Answer 1

The most secure choice for such a device would be opting for radio waves. This is because radio waves have a longer wavelength, which allows them to penetrate objects and be less likely to be affected by interference or obstacles. Additionally, radio waves are less harmful to organisms compared to X-rays or gamma waves, making them a safer choice for use in such devices. Ultraviolet waves, on the other hand, are not suitable for this purpose as they have a shorter wavelength and are more easily absorbed or scattered by objects.
