frequency-dependent conductance
a succession of frequency ranges each beginning where the previous leaves off called a frequency band
a radio wave that has a wave length of 1000 meters or more, called long wave
an apparatus used to measure the length of electromagnetic waves
wavelength and frequency are, of course, related reciprocally- F.A.Geldard
a wave number characteristic of the wave spectrum of each element
a unit of the metric system used to measure the length of X-rays or other rays
a radio wave with a wavelength longer than a kilometer (a frequency below 300 kilohertz)
a spectrum, produced by a luminous gas or vapour, in which distinct lines characteristic of an element are emitted by its atoms, called a line spectrum
an aerial half a wavelength long consisting of two rods connected to a transmission line at the center
