22–23p. Abstract: Ever since Galileo climbed a dark hill with a lamp, scientists have been experimenting with ways to measure the speed of light.1 Galileo’s method of sending a signal out to a distant hill and getting a response back did not prove accurate at the time. However, since the invention of lasers and oscilloscopes, this experimental method works well and provides fairly accurate results.2 In this paper, recent advances in technology are used to bring the experimental cost down to $100 while increasing the accuracy of the results to better than 3%. ***______{For Hard Copy, Please visit Library.}________*** Operational amplifier| Analog circuits| Oscilloscopes| Photodiodes| Signal generators| Fundamental constants| Lasers 0031-921X https://doi.org/10.1119/5.0124070 https://doi.org/10.1119/5.0124070 240508 20240508073456.0
