What is ELF/VLF Research? ELF/VLF stands for Extremely Low Frequency and elf slots casino sister sites Very Low Frequency, and refers to the range 300 Hz to 30 kHz. The Stanford ELF/VLF group is actively exploring how these radio waves interact with the Earth’s surface. What is elf slots casino sister sites ELF/VLF Research? ELF/VLF stands for Extremely Low Frequency and Very Low Frequency, and refers to the range 300 Hz to 30 kHz. Lightning-ionosphere impacts. Lightning has broader impacts than just the flash of light and thunder. For instance, certain kinds of lightning can cause a brief discharge tens of miles above the cloud, called sprites, which were predicted in the 1920s but not discovered by scientists until 1989. In fact, some lightning can even accelerate electrons to speeds enormously close the speed of light, producing gamma rays that we usually only see in association with collapsing stars and black holes. The Stanford ELF/VLF group is actively engaged in understanding how lightning impacts out planet’s ionosphere and magnetosphere. Read more about studies of sprites and transient luminous phenomena, and terrestrial gamma-ray flashes. How did ELF/VLF Research Come About? The history of ELF/VLF observation dates back to the late 1800’s, when the first telegraph lines were laid down. The first operators reported hearing bizarre sounds that they described as clicks and tweeks, particularly on a day with lightning, which we now know were probably just sferics being picked up by their telegraph line, basically acting like an antenna. Later, in World War I, soldiers operating communication lines reported hearing strange sounds consisting of a falling tone, sounded like someone was whistling. Sites Son Yazılar.
