Which phenomenon increases during radio-wave propagation in moist air?

💡 Explanation

Signal attenuation increases due to absorption, which is a form of electromagnetic absorption, because water molecules absorb radio-wave energy converting it into heat, therefore the signal weakens, rather than penetrating better or interfering constructively.
