A Some devices electromagnetic waves to find the location and speed of an object in these devices, the waves are emited and then relle off of the chject and returned back toward the device. By knowing the speed of the wave
and the time takes the wave to em to the device, the distance that the wave traveled can be calculated. Which type of wave would be safest to use in this type of device?
Gamma wawes would be the satest choice because they wavel the tastese.
Uvices would be treatest choice because they are easiest to visually detect
Radio waves would be the satest choice because they are the last damaging to organisms.
Xes would be the test choice because they are able to travel through many types of materials
