A k-factor is simply a value to represent the bend that is occurring. k-factor 1 = No bending k-factor <1 = Signal bending away from the earth k-factor >1 = Signal bending toward the earth k-factor 4/3 = Normal atmospheric conditions. Signal slightly bending toward the earth Causes Outdoor: Water vapor
Snell
Refraction between two surfaces is also referred to as reversible because if all conditions were identical, the angles would be the same for light propagating in the opposite direction. Snell's law is generally true only for isotropic or specular media (such as glass). See more Snell's law (also known as Snell–Descartes law and ibn-Sahl law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or … See more Snell's law can be derived in various ways. Derivation from Fermat's principle Snell's law can be derived from Fermat's principle, which states that the light travels the path which takes the least time. By taking the derivative of the optical path length, … See more In many wave-propagation media, wave velocity changes with frequency or wavelength of the waves; this is true of light propagation in most transparent substances other than a vacuum. These media are called dispersive. The result is that the angles … See more Ptolemy, in Alexandria, Egypt, had found a relationship regarding refraction angles, but it was inaccurate for angles that were not small. Ptolemy was confident he had found an accurate … See more Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of … See more When light travels from a medium with a higher refractive index to one with a lower refractive index, Snell's law seems to require in some … See more In a conducting medium, permittivity and index of refraction are complex-valued. Consequently, so are the angle of refraction and the wave-vector. This implies that, while the surfaces of constant real phase are planes whose normals make an … See more WebNov 28, 2014 · Radio Frekuensi (RF) atau Gelombang Radio adalah tingkat osilasi dalam kisaran sekitar 3 kHz sampai 300 GHz, yang sesuai dengan frekuensi gelombang radio, dan arus bolak-balik yang membawa sinyal radio.
