the ghosts move 2 like if u have a room with light sensors the light will still turn on
motion detector
If you are asking how it detects ghosts, then the answer is that is likely does not detect ghosts, as there has been no demonstration that ghosts exist, let alone that there is an effective means to detect them.
No as ghosts are not real.
A metal detector can detect all types of metal....depending on in what type of soil it is in.
the function of a diode detector is to detect stuff
thermometer
no
In 1209 the first motion detector was intended by Ben Ray Alexander wheat
With a ultraviolet light detector.
-- If the detector is designed to detect wave characteristics, then light exhibits all the characteristics and behavior of a wave when it encounters that detector. -- If the detector is designed to detect particle characteristics, then light exhibits all the characteristics and behavior of a particle when it encounters that detector.
Yes, and you wouldn't need the motion detector.
