The Red-belly snake (Storeria occipitomaculata) is a relatively small snake that rarely exceeds 12 inches in length. It is native to North America, Mexico and Central America, and it is NOT venomous.
The electromagnetic frequency of a wave is defined as how many times the peak of this oscillation moves past a point each second. This has a major effect on the properties of the wave, including its energy.
When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. These frequencies make up part of the electromagnetic radiation spectrum: 1  Ultra-low frequency (ULF) -- 0-3 Hz.2  Extremely low frequency (ELF) -- 3 Hz - 3 kHz.3  Very low frequency (VLF) -- 3kHz - 30 kHz.4  Low frequency (LF) -- 30 kHz - 300 kHz.hese frequencies make up part of the electromagnetic radiation spectrum: 1  Ultra-low frequency (ULF) -- 0-3 Hz. 2  Extremely low frequency (ELF) -- 3 Hz - 3 kHz. 3  Very low frequency (VLF) -- 3kHz - 30 kHz. 4  Low frequency (LF) -- 30 kHz - 300 kHz.
