The first radiograph took about 15 minutes and depicted whose hand?

• A. The hand of his wife
• B. The hand of a volunteer
• C. His wife's hand
• D. A cadaver's hand

Answer: (C)

The first radiograph demonstrates how X-rays reveal internal anatomy by silhouette imaging. Wilhelm Conrad Roentgen created the famous initial image in 1895 by taking a long-exposure photo of his wife’s hand to show that bones could be seen through soft tissue. The exposure took about 15 minutes, and the resulting image clearly shows the bones and a wedding ring. This historical moment established X-ray radiography as a diagnostic tool. The other options don’t fit the well-documented origin: the landmark image was not of a cadaver or a volunteer.
