Rayleigh disk experiment
WebTorque on Rayleigh disk in a resonating tube, for high pitch sounds.---In the case of a disk 15 cm in diam. in a tube 16 cm in diam., a study of the deflection as a function of wave-length, 4 to 28 cm, showed that for a wave-length of 28 cm the disk tended to set itself parallel to the axis of the resonator, and hence was deflected in a direction opposite to the usual one. … WebFeb 6, 2024 · Following, the Rayleigh backscattering signals are digitized by a data acquisition card (DAQ, Spectrum M4i.4450-x8) and are saved to a solid-state disk (SSD) for further processing. The function generator generates pulse signals to drive AOM through the radio frequency driver and, at the same time, outputs synchronous pulse signals to DAQ …
