HELP!! Which type of
electromagnetic radiation is used in security baggage
scanners, and why?
A. Radio, because its low energy makes it safe for the machine
operators
B. Gamma rays, because they are high-frequency waves, which
causes them to easily bend around the objects in the baggage
C. X-rays, because they either pass through or are absorbed by the
objects in the baggage, creating an image of the objects
D. Infrared, because the waves are reflected by the objects in the
baggage, creating an image of the objects
