The cardboard in Colleen's simulation symbolizes the bones that look white in an X-ray. This is because, in an X-ray, bones and dense tissues block the radiation, appearing white on the resulting image, while other areas that are less dense (like soft tissues) allow more radiation through, appearing darker.
Question
Colleen replicates an X-ray machine by covering an open shoebox with a screen and positioning a square cardboard piece in the center. She uses sand to simulate X-ray radiation, sprinkling it over the screen. Upon removing the screen, she observes an outline of the square cardboard. What does the cardboard symbolize in her simulation?(1 point)
