Missing FiguresCharacteristics of LightThere are a few fundamental characteristics of escape that are useful to be aware of before proceeding with the discussion on how CCDs and Film can function to save a useful, meaningful image. iodine of these important fundamental qualities is the fact that visible light is electromagnetic radiation.Electromagnetic Radiation, Photons, and Energy LevelsElectromagnetic radiation has many different classifications. Some such classifications intromit AM/FM Radio Waves, microwaves, visible light, x-rays, and gamma rays. A key factor in these classifications is that each different type or level of electromagnetic radiation contains different faculty levels. These energy levels are determined by the speed or rate that charges from a given source move to micturate an electric field (for instance, moving charges through an antenna or lightbulb) (Serway 1090). Hence, this oscillating electric field has two very important characteristics it has a freq uency and a wavelength. Furthermore, light can also behave as a particle in some instances. This particle of light is called a photon, and is essentially the amount of energy that a light wave has at a certain frequency (the energy of a photon is not dependent on the intensity of the light, but quite an only dependent upon its frequency) (Serway 1107). It is this duality of light that allows CCDs and film to function as they do, as energy is transferred to materials through light via. photons.Since the energy of a photon is only link to its frequency, an equation (discovered by Einstein) relates photons to the electrons they produce byE = h * fWhere E is the energy of the produced electron, h is Plancks constant (6.63 * 10-34 J... ...graphic Sensitivity. 2001. 31 Mar. 2003 Gambhir.
