Low frequency gravitational wave
Web5 feb. 2024 · Gravitational waves passing through the formation flight in space change these distances by a trillionth of a meter. LISA will measure low-frequency gravitational waves with oscillation periods ranging from 10 seconds to more than half a day, which cannot be observed with detectors on the earth. Web1 feb. 2024 · Einstein's theory predicts (and recent observations have confirmed) that the speed of gravitational waves is v = c, regardless of their frequency. Thus, higher-frequency waves have shorter wavelengths, and lower-frequency waves have longer wavelengths, just as with electromagnetic waves.
