1 1 CAPA #11 due today. CAPA #12 available – due next Friday. Reading in Chapter 24 for next week. We will cover the wave nature of light next week, and then a little on geometrical optics (Chapter 23). 2 Consider the follow wire loops (1-4 are identical, 5 is longer). All loops move with identical speed |v|. There is a magnetic field in Region I, and none in Region II. The magnetic flux through loop 2 is: A) zero B) non-zero The rate of change with time of magnetic flux through loop 2 is: A) zero B) non-zero The rate of change with time of magnetic flux through loop 4 and 5 is: A) greater for loop 4 B) greater for loop 5 C) exactly the same for loop 4 and 5 3 Shaking a single electron (or many) creates an Electromagnetic wave (traveling at the speed of light!) http://phet.colorado.edu/new/index.php Moving charge Æ Transmitting Tower Receiving Tower Æ Antenna 4 Demonstration Does it matter which way the antenna is oriented? 5
