1. The problem statement, all variables and given/known data We're working through the first Microwave Optics lab described in the following PASCO Scientific manual: intro.phys.psu.edu/class/p457/experiments/html/pasco_microwave_optics_WA-9314B.pdf We're using a slightly modified version of this setup, with a voltmeter hooked up to the receiver. As the receiver is moved away from the transmitter in 2 cm increments, the meter reading is recorded. We want to demonstrate that the intensity is proportional to the inverse square of the distance between the transmitter and receiver. Question: What is the relationship between intensity and our voltage reading at each position? Can we reasonable assume that the intensity is proportional to the square of the voltage? 2. Relevant equations 3. The attempt at a solution E field is proportional to Voltage. Intensity is proportional to square of E field. Therefore, Intensity is proportional to square of Voltage reading. Have we gone off in a wrong direction?
