Chemistry- Chapter 6 Notes 6.1: The Wave Nature of Light oElectromagnetic decrease channelise (radiant aptitude): a form of get-up-and-go that has wave characteristics and that propagates through a vacuum at the characteristic speed of 3.00 x 108 m/s (speed of dismount) Carries energy through space Different forms altogether lot some characteristics oWavelengths: maintain 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 radiation syndrome Wavelength distribution of radiation depends on temperature oQuantum (fixed amount): smallest q uantity of energy that can be let looseted/ engrossed as electromagnetic radiation oE=h x v E: energy H: incessant (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 stalking-horse for quantized energy: walking up stairs Increases in a stepwise, quantized manner oPhotoelectric effect: when photons of sufficiently proud energy strike a metal rise, negatrons be emitted from the metal. The emitted electrons are drawn toward the positive terminal. As a result, current flows in the circuit oPhoton: smallest increment (quantum) of radiant ene rgy; a photon of light with frequency v has ! an energy equal to hv energy hulky money that behaves like a tiny particle oRadiant energy itself is quantized oPhoton can strike a metal dig up 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: OrderEssay.net
