| KillGorack | 2023-07-22 13:16:21 | infrasonic Infrasonic waves have the longest wavelengths among the options listed. Infrasonic waves are sound waves with frequencies below the audible range of human hearing (typically below 20 Hz). Since wavelength is inversely proportional to frequency (wavelength = speed of sound / frequency), lower frequencies result in longer wavelengths. Therefore, the infrasonic range corresponds to the longest wavelengths. |
