3/28/2004 H133 Spring 2004 1 Chapter 3 So light was found to be a wave in the early 1800’s…everyone was happily studying optics. Maxwell (1860’s) established that light was made up of electronic and magnetic fields that were oscillating: As we will soon see a very interesting phase of physics was about to begin. You have already learned about relativity. One of the first “loose ends” that hinted at the emergence of quantum mechanics was called the photoelectric effect . Various experimentalist came across this feature and saw that many different metals showed this same feature. Let’s construct an idealize experiment to understand the properties of the photoelectric effect. e - light metal

3/28/2004 H133 Spring 2004 2 Photoelectric Effect Setup Mode #1 (Close ammeter switch) ± Ammeter has R~0 ± Measure I ± I proportional to # of electrons liberated by the light Mode #2 (open ammeter switch, close voltmeter switch) ± Voltmeter has R ~ infinite ± Measure Potential difference between plates ∆φ . ± Electrons collected on the anode remain on the anode. It becomes negatively charged while the cathode becomes positively charged.
