Electromagnetic spectrum the range of different kinds of electromagnetic radiation Electricmagnetic energy is characterized by a frequency, a wavelength, and an amplitude Frequency (ν "nu" ) the number of wave maxima that pass by a fixed point per unit time. Hertz (Hz) a unit of frequency; 1Hz = 1s^-1 Wavelength (lambda) the length of a wave from one maximum to the next (Section 3.1) Amplitude a wave's height measured from the midpoint between peak and trough wavelength equation Wavelength * Frequency = Speed of light"lambda"(m) * "nu"(Hz) = c (m/s)rewritten"lambda" = c / "nu"or"nu" = c / "lambda" Line spectrum the wavelengths of light emitted by an energetically excited atom Balmer–Rydberg equation an equation that accounts for all lines in the hydrogen spectrum 1 / "lambda" == R(oo) ((1/m^2) - (1/n^2)) R(oo) = Rydberg constant == 1.097*10^-2 nm^-1 Photon the smallest possible amount of radiant energy; a quantum photon energy equation E = h*"nu" == hc/"lambda" h = plack's constant: 6.626*10^-34c = speed of light: 3.00*10^8 Avogadro's number 6.022*1023 unit of mole. joule is a unit of energy1 j = 1(kg/m2)/s2 the intensity of a light beam is a measure of the number of photonsin the beam a measure of energies of the photons frequency Quantum the smallest possible amount of radiant energy de Broglie equation an equation that relates mass, wavelength, and velocity, m = h/λνλ = h/mν m: massh: placks constant Quantum mechanical model a model of atomic structure that concentrates on an electron's wavelike properties Heisenberg uncertainty principle The position and the velocity of an electron can never both be known beyond a certain level of precision (change in x"position")(Change in Mass "nu") => h / 4"pie" AuthorRayen ID43154 Card SetOSU CH 201 Ch3 DescriptionOsu Ch 201 Updated2010-10-18T23:28:20Z Show Answers
