  • Unit Objectives

    By the end of this unit, you should be able to:

    • Explain the basic behavior of waves, including travelling waves and standing waves
    • Describe the wave nature of light
    • Use appropriate equations to calculate related light-wave properties such as period, frequency, wavelength, and energy
    • Distinguish between line and continuous emission spectra
    • Describe the particle nature of light
    • Extend the concept of wave–particle duality that was observed in electromagnetic radiation to matter as well
    • Calculate deBroglie wavelengths
