Question

Quizplus · Accepted Answer

Water molecules strongly absorb electromagnetic radiation in the infrared region of the spectrum. This is because water molecules have a dipole moment and undergo rotational and vibrational motions, which absorb energy in the infrared range. Other regions of the spectrum, such as visible and ultraviolet, are not absorbed as strongly by water. Therefore, choice A is the best answer.
