Document Summary
Lecture 32: light energy: key idea: energy associated with movement of electrons can be converted into light, wrap-up points: Light of a speciic wavelength has a speciic energy smaller "s correspond to higher energies. Light can also be viewed as consising of packets of energy called photons carrying speciic energy. The intensity of light is then related to the number of photons. Blackbody radiaion: the temperature of an object determines the range of energies (or colors) of the light emited by the object. Only objects at 0 k do not emit radiaion: study guide notes: Many exothermic reacions and objects at high temperature generate light. Any object consising of many atoms or molecules is a source of electromagneic radiaion as long as it has a temperature greater than 0 k. Increasing the temperature of a blackbody shits the emission spectrum to higher frequencies and shorter wavelengths. Intensity of emited radiaion increases exponenially with temperature.
