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.

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.
