524073 - Laser motion sensor S

For high-resolution, contactless recording of distance and the time it takes light to cover that distance using CASSY (5210.524013, 5210.524006, 5210.524005W, 5210.524018) or the universal physics measuring instrument (5210.531835). The time-dependent measurement of distance allows high-resolution and non-contact recording of motion (such as on a track or in a free fall). The time delay measurement between laser motion sensor S and a reflector can be used to determine the speed of light in different media (air, glass, etc.). As a reflector a piece of retro-reflective sheeting supplied is glued to an object (e.g., trolley and rider).
