Vesnalui [34]

Answer:

An X-ray is done to diagnose the position of bones in the body whether its broken or not or in right place or not.

An X-ray machine is turned on to provide a visual of the bones showing bone condition. When the machine is turned on, X-ray travel through the body tissues, and due to the presence of calcium in bones, they absorb more X-rays, thus bones appear white against the black background of a radiograph.

These white bones on the radiograph will show the position of bones whether it's broken or not.

So, both the visuals that is X-ray and drawing showing visuals (the bones appear white) contribute valuable data to the given situation.
