A whistler is a very low frequency (VLF) electromagnetic (radio) wave generated by lightning. Frequencies of terrestrial whistlers are 1 kHz to 30 kHz, with a maximum amplitude usually at 3 kHz to 5 kHz. Although they are electromagnetic waves, they occur at audio frequencies, and can be converted to audio using a … Se mer The pulse of electromagnetic energy of a lightning discharge producing whistlers contains a wide range of frequencies below the electron cyclotron frequency. Due to interactions with free electrons in the ionosphere, the … Se mer Whistlers were probably heard as early as 1886 on long telephone lines, but the clearest early description was by Heinrich Barkhausen in … Se mer • Dawn chorus (electromagnetic) • Electromagnetic electron wave • Hiss (electromagnetic) • Atmospheric noise • Radio atmospheric Se mer A type of electromagnetic signal propagating in the Earth–ionosphere waveguide, known as a radio atmospheric signal or sferic, may escape the ionosphere and propagate outward into the magnetosphere.
