Shedding Light on the Subject.
Keller, Brian A.
Mathematics Teacher, v91 n9 p756-62,767-71 Dec 1998
Presents an activity in which students use mathematical ideas to understand how the intensity of light changes as light passes through water or similar partial barriers, by using a calculator-based laboratory device to record light intensity. Continues with a structured series of questions involving the use of difference equations with which students determine an exponential-decay model for the intensity data. (ASK)
