CHEMISTRY REVIEW – ch. 1-3, 12 Electromagnetic Radiation- o Wavelike behavior and travel at the speed of light in a vacuum o Electric and magnetic fields that oscillate in planes mutually perpendicular to each other and to the direction of propagation through space. o Characterized by wavelength, frequency and speed o C = wavelength x frequency C = 3.0x10^8 o Wave Properties: interference (constructive, destructive), oscillating fields o Particle Properties: photons of light, has a mass Electromagnetic Spectrum o Visible light = 400 – 700nm (blue to red) ROY G BIV o P. 512 o E = hxfrequency (v) o C = wavelength x frequency (v) Louis de Broglie Theory o Any moving particle with mass and velocity should have a corresponding wavelength o Wavelength = h/p = h/(massxvelocity) o Can treat electron as a wave When confined to a region around the nucleus, electron = behaves as a standing wave PHOTOELECTRIC EFFECT o Devised by Albert Einstein o 4 OBSERVATIONS
