How to determine the speed of a beam splitter
A beam splitter is placed in front of the image at s so that a second image may be produced at s' and viewed through a measuring microscope. The Foucault method of measuring the Speed of Light consists of a Laser Beam going through a beam splitter, then reflecting off a high speed rotating mirror towards a fixed mirror. INTRODUCTION: Historical Note: Galileo tried to measure the speed of light by timing the round trip time of. The speed of light was measured using the Foucault method of reflecting a beam of light from a rotating mirror to a fixed mirror and back creating two separate reflected beams with an angular displacement that is related to the time that was required for the light beam to travel a given distance to. Calculate the speed of light, estimate your error and compare to literature. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications.
