Final answer:
X-ray is the best diagnostic tool for bone injuries because of its higher penetrating energy. CT scans can also be used to produce cross-sectional views of the bones.
Step-by-step explanation:
The best diagnostic tool for bone injuries is X-ray. X-rays have higher penetrating energy than radio waves and are commonly used to image broken bones. Computed tomography (CT) scans, which use computer processing of X-ray measurements, can also be used to produce a cross-sectional view of the bones.
