CHE 201 Lecture Notes - Lecture 14: Electromagnetic Spectrum, Standing Wave, Black-Body Radiation
Document Summary
Hess"s law is the change in enthalpy that occurs when reactants are converted to products in a reaction is the same whether the reaction takes place in one step or in a series of steps. Standard enthalpy of reaction hrxn is defined as the enthalpy of a reaction carried out under standard conditions o o. Chapter 6 quantum theory and the electronic structure of atoms. The electromagnetic spectrum is the continuum of radiation: includes radio waves, microwave radiation, infrared and ultraviolet radiation, x rays, gamma rays, and visible light. Wavelength (lambda) is the distance between identical points on successive waves. Frequency v (nu) is the number of waves that pass through a particular point in 1 second. Amplitude is the vertical distance from the midline of a wave to the top of the peak or the bottom of the trough. Speed of light through a vacuum (c) is 2. 99792458 x 108m/s. Maxwell proposed that visible light consisted of electromagnetic waves.
