Bones absorb greater amounts of incident X-rays than flesh. This is because:
Correct answer: D. Bones contain material of high densities
- A. Bones lie between the flesh
- B. Bones are light in color
- C. Bones contain material of low densities
- D. Bones contain material of high densities
Explanation
Bones absorb more amounts of incident X-rays than flesh because bones contain a very large amount of calcium which makes it highly dense.The colour of bones has nothing to do with radiation absorption,nor does the position of bones in flesh.It is a fact.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
