Tufts University – Chem 1 – Spring 2007 Topics for Exam II 1.1. Wave aspect of the electromagnetic radiation: wave frequency and wavelength, c = λν . Electromagnetic spectrum, relative frequencies and wavelengths of radio and microwaves, IR, vis (400-700 nm), and UV light, X- and γ-rays. 1.2. Incandescence as emission of photons by hot objects (no formulas required). Particle aspect of electromagnetic radiation, quanta of energy, Plank’s constant, E = h ν. Photoelectric effect and its explanation by Einstein. KE = h ν-Φ. 1.3. Wave-particle duality and de Broglie: λ = p h ; p = mv. Diffraction of subatomic particles as a proof of de Broglie’s hypothesis. 1.4. Uncertainty principle and Heisenberg: ( x)( p)≥ h/4 π; p = mv. 1.5. Wavefunction of electron in atom. (Conceptual understanding; no calculations required). Born’s interpretation of ψ 2 as the probability density. Schrodinger equation. (Conceptual understanding: it allows for the calculation of E n from known ψ n for and for the determination of possible ψ n ’s in the hydrogen atom). Omit particle in the box.
