interferometers - 2024 PACE NSC

Question

These devices are “tuned” with signal recycling, which was first implemented in GEO600. Noise curves for these devices plot frequency versus strain measured in inverse-square root hertz. A 2015 “Advanced” expansion to some of these devices added transduction from a type of these devices in which a cavity is formed between two moveable wedged optical flats. The Fabry–Pérot etalon (20[1])is (20[1])a type of these devices. (20[1])A sandstone block in a pool of mercury (20[1])was (20[1])central (20[1])to one (20[1])of these (20[1])devices (20[3])at (20[2])(*) Case Western Reserve. (10[3])The existence of (10[1])the (10[1])luminiferous aether (10[1])was debunked with one of these (10[1])devices (10[2])by Michelson and Morley. (10[1])For 10 points, (10[1])name these devices that measure a namesake optical phenomenon (10[2])and are the “I” in “LIGO.” (10[1])■END■ (10[6])

ANSWER: interferometers [accept laser interferometers; accept Fabry–Pérot interferometers; accept Laser Interferometer Gravitational-Wave Observatory; prompt on gravitational wave detectors by asking “what device is central to gravitational wave detectors?”; prompt on LIGO before read by asking “what device is central to LIGO?”; prompt on lasers by asking “in what devices are lasers being used?”; prompt on Fabry–Pérot etalons] (Advanced LIGO was completed in 2015.)
