For high-resolution, contactless recording of distance and the time it takes light to cover that distance using CASSY (524 013, 524 006, 524 005W, 524 018) or the universal physics measuring instrument (531 835). 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).
