Which of the following is least reasonable regarding the "water hole"? Group of answer choices It consists of frequencies which are greater than the frequencies of atmospheric emissions. It relates to the natural frequencies of vibration of hydroxyl (OH) and hydrogen (H), respectively. It occurs in that part of the electromagnetic spectrum where the galactic "noise" from stars and interstellar clouds is minimized. It is considered the "electromagnetic oasis" for interstellar communication. It corresponds to wavelengths in the 18-21 cm range.
