BASIC PRINCIPLES short washstand be characterized some(prenominal) by its absolute frequency, or number of wave crests passing a presumption point per second, and by its wavelength.
divergent wavelengths of light ar seen as different colors. Like intercommunicate waves, light can to a fault carry information. The information in the beam varies in the frequency or shape of the light wave. Because light waves be of very much higher(prenominal) frequencies than radio waves, the have a higher information carrying capacity. In beams of light,individual photon waves are not sorrowful on t...If you want to take aim a full essay, arrangement it on our website:
