Study Guide 8.1 Electric and magnetic fields propagates as waves through empty space or a medium . Electromagnetic waves are created by the acceleration of a charged particle. C = wavelength times hz *c is constant at 3x10^8, thus wavelength and frequency are inversely related. Constructive and destructive interference of waves helps on a grooved surface (cd) causes the diffraction of colors. Colors are very energy level specific, and since each element has only a limited energy level, they can only emit certain colors (atomic spectra). Ionization energy: energy required to remove the electron Kinetic energy= energy- ionization energy Quantum Theory energy levels are limited and specific; basically a measurement. Planck’s Equation : E=hv *for one mol of electrons; the higher the frequency the stronger (ex. Radio vs gammarays) Photoelectric effect - Has to pass a certain threshold - Increase in intensity only increases/decreases electrons absorbed/produced. * Analogy: flashlight to super strong light, only area increases
