The flashcards below were created by user Rayen on FreezingBlue Flashcards. What would you like to do?


  1. Electromagnetic spectrum
    the range of different kinds of electromagnetic radiation
  2. Electricmagnetic energy
    is characterized by a frequency, a wavelength, and an amplitude
  3. Frequency (ν "nu" )
    the number of wave maxima that pass by a fixed point per unit time.
  4. Hertz (Hz)
    a unit of frequency; 1Hz = 1s^-1
  5. Wavelength (lambda)
    the length of a wave from one maximum to the next (Section 3.1)
  6. Amplitude
    a wave's height measured from the midpoint between peak and trough
  7. wavelength equation
    • Wavelength * Frequency = Speed of light
    • "lambda"(m) * "nu"(Hz) = c (m/s)
    • rewritten
    • "lambda" = c / "nu"
    • or
    • "nu" = c / "lambda"
  8. Line spectrum
    the wavelengths of light emitted by an energetically excited atom
  9. 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
  10. Photon
    the smallest possible amount of radiant energy; a quantum
  11. photon energy equation
    E = h*"nu" == hc/"lambda"

    • h = plack's constant: 6.626*10^-34
    • c = speed of light: 3.00*10^8
  12. Avogadro's number
    6.022*1023 unit of mole.
  13. joule
    • is a unit of energy
    • 1 j = 1(kg/m2)/s2
  14. the intensity of a light beam is a measure
    of the number of photonsin the beam
  15. a measure of energies of the photons
    frequency
  16. Quantum
    the smallest possible amount of radiant energy
  17. de Broglie equation
    • an equation that relates mass, wavelength, and velocity, m = h/λν
    • λ = h/mν
    • m: mass
    • h: placks constant
  18. Quantum mechanical model
    a model of atomic structure that concentrates on an electron's wavelike properties
  19. 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"
