Quizplus · Accepted Answer

AM radio signals are most susceptible to interference from sources such as lightning because they use amplitude modulation, which means that the strength of the signal carries the information. Interference from lightning can disrupt the strength of the signal, causing static and other disruptions. FM signals are less susceptible because they use frequency modulation, which means that the frequency of the signal carries the information.
