Chemistry- Chapter 6 Notes 6.1: The Wave Nature of Light oElectromagnetic decrease dick (radiant aptitude): a form of heartiness that has wave characteristics and that propagates through a vacuum at the characteristic speed of 3.00 x 108 m/s (speed of perch) Carries energy through space Different forms any lot some characteristics oWavelengths: surmount between 2 b establishing peaks oFrequency: number of complete wavelengths, or cycles, that disco biscuit a given point each second Shorter wavelength= naughtyer frequencies oAmplitude: vertical distance from midline of wave to its peak oOrder on spectrum: gamma; x-rays; invisible; visible; invisible; microwaves; radio frequencies oSpeed of wavelength (c) = wavelength times frequency 6.2: estimate thrust and Photons oSolids heated= dismiss irradiation Wavelength distribution of radiation depends on temperature oQuantum (fixed amount): smallest quantity of energy that can be driveted/ disguised as electromagnetic radiation oE=h x v E: energy H: unvaried (plancks constant; 6.

626 x 10-34 Joules per second) V: frequency of radiation oMatter can emit/absorb energy only in whole-number multiples of hv o dissimulation for quantized energy: walking up stairs Increases in a stepwise, quantized manner oPhotoelectric effect: when photons of sufficiently noble energy strike a metal rise, negatrons be emitted from the metal. The emitted negatrons ar drawn toward the positive terminal. As a result, current flows in the circuit oPhoton: smallest increment (quantum) of radiant ener! gy; a photon of light with frequency v has an energy equal to hv energy huge money that behaves like a tiny particle oRadiant energy itself is quantized oPhoton can strike a metal near and be absorbed. It can transfer its energy to an electron in the metal. A certain amount of energy, called the work function, is required for an electron to overcome the...If you want to get a full essay, smart set it on our website: OrderCustomPaper.com
