The beam splitter is moved from one to two

The beam of light from the laser strikes the beam-splitter, which reflects 50% of the incident light and transmits the other 50%. The incident beam is therefore split into two beams; one beam is transmitted toward the movable mirror (M1), the other is reflected toward the. A beam splitter or beamsplitter is an optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. The other. The experiment belongs to a general class of "double path" experiments, in which two diffracted waves reconverge, creating an interference pattern. In the basic version of this experiment, a coherent. [pdf]
