When John broke his arm, the doctor took an x-ray of John's arm. John had never seen an x-ray before. He asked the doctor how the x-ray was able to show his bones but not his skin and other tissue. Which explanation would the doctor best provide to John? ) X-rays have lower energy than visible light and therefore produce a black background behind the bone image. ) X-rays have higher frequency than gamma rays and therefore pass through skin and bone. ) X-rays have higher frequency than visible light and therefore can pass through skin and tissue but not through the bone. ) X-rays have lower frequency than infrared light and therefore penetrates through the bone.
