Chem 1320 1st Edition Lecture 14Outline of Last Lecture I. Average Molecular SpeedII. Real GassesIII. Van der Waals Equation of State Outline of Current Lecture I. Nature of the ElectronII. Max Plank’s InsightCurrent LectureI. Nature of the ElectronThe electron has a negative charge and e= 1.602 x 10-19. The nature of light is referred to as electromagnetic radiation. The speed is 2.998 x 109m/s or 3x108m/s. Frequency is the number of oscillations of a wave per second (hertz).Speed= 120m/4s= 30m/s= 67mph. The wavelength tracks 120/4= 30m 120/6= 20m Frequency is 4/4s = 1.0s-1Wavelength x frequency (30m/s)(1/sec)=30m/s(20m)(1.55s-1)=30m/sEnergy is when frequency goes up volume goes downWhat is the frequency of light if it’s wavelength is 700m10-1 m= 1nmII. Max Plank’s Insight Classical physics (waves) could predict long wavelength behavior. These notes represent a detailed interpretation of the professor’s lecture.
