Some devices use electromagnetic waves to find the location and speed of an object. In these devices, the waves are emitted and then reflected off of the object and returned back toward the device. By knowing the speed of the wave and the time it takes the wave to return 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?
