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.
The frequency of an RF signal is usually expressed in terms of a unit called the hertz (Hz). One Hz equals one cycle per second. One megahertz (MHz) equals one million cycles per second. Different forms of electromagnetic energy are categorized by their wavelengths and frequencies.or example, the unit volts per meter (V/m) is used to measure the strength of the electric field and the unit amperes per meter (A/m) is used to express the strength of the magnetic field. RF waves can be characterized by a wavelength and a frequency.
