CHM 132 Chapter Notes - Chapter 12: Diffraction, Emission Spectrum, Bohr Model
Document Summary
Wavelength the distance between two consecutive peaks or troughs in a wave. Frequency the number of waves per second that pass a given point in space. Cycles is a common word to explain the pattern of light: cycles/sec = hertz. Dual nature of light light has both the characteristics of a wave and a particle. Important study was when a high energy discharge is passed through hydrogen gas and the gas absorbed the energy causing some of the h-h bonds to break. Hydrogen molecules are now excited and release their energy by emitting light to produce an emission spectrum. Continuous spectrum the spectrum that occurs when white light passes through a prism and contains all of the colors. Hydrogen emission spectrum does not include all of the colors only some lines creating a line spectrum. Line spectrum demonstrates the wavelengths in the light as lines of color with each line matching a specific wavelength.
