The order of increasing wavelength (and decreasing energy) of the given radiations is:
Gamma Rays > X-Rays > Visible Light > Radio waves
X-rays due to the short wavelength and higher energies have the ability to penetrate through soft tissues like the skin or get absorbed by hard tissues like the bones. Thus, when the human anatomy is exposed to X-rays, bones appear white whereas the skin/tissues appear gray.
Ans: A) X-rays are used by doctors to view skeletal structures
<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>
The water evaporates into the clouds
