  • ⚛️ Letzte Woche hatte mein Physik-LK die Möglichkeit an der Master Class zum Michelson-Interferometer an der @tubraunschweig teilzunehmen. Selbst aufgebaut, kalibriert und gemessen bleibt sicher mehr hängen, als beim Demonstrationsversuch.

What “interferometer” means

Wiktionary · Wikipedia

interferometer

  • nounAny of several instruments that use the interference of waves to determine wavelengths and wave velocities, determine refractive indices, measure small distances, temperature changes, stresses, and many other useful measurements.
Full entry on Wiktionary →

Interferometry is a technique which uses the interference of superimposed waves to extract information. Interferometry typically uses electromagnetic waves and is an important investigative technique in the fields of astronomy, fiber optics, engineering, metrology, optical metrology, oceanography, seismology, spectroscopy, quantum mechanics, nuclear and particle physics, plasma physics, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, velocimetry

#interferometer across platforms

every network with a public tag surface

Follow #interferometer straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/interferometer
