05 EM Radiation

Important Concepts for This Unit (Study Guide)

Section 5.2-Properties of Light

    Properties of Light

        Wavelength, frequency, velocity conversions (where velocity is speed of light).

        Energy: E=hf

    EM Spectrum

        Regions in the EM spectrum (Gamma rays, x-rays, UV, visible light, IR, microwaves, radio) 

        Students should be able to sort this list in terms of energy, wavelength, and frequency

        Figures 5.5, 5.6, and 5.7

        Mathematical Insight 5.1

How is Energy Stored in Atoms?

    Energy Levels in Atoms

    Energy Level Transitions

    Figure 5.12


Section 5.4-Learning from Light

    Continuous spectra

    Emission spectra

    Absorption spectra

    Line spectra (emission and absorption) as related to energy levels in atoms

    Figures 5.14, 5.15

Laws of Thermal Radiation

    Figure 5.19

    Stefan-Boltzmann Law, f=\sigma * T^4

    Wien’s Displacement Law, \lambda_peak = 2.9E6/T

    Mathematical Insight 5.2
