Daim duab 1. Daim duab kos duab rau Marconi Wavemeter Number Ib. Xyoo 1906, Guglielmo Marconi thawj zaug qhia Marconi Wavemeter Number One hauv tebchaws Askiv. Thawj qhov kev lag luam wavemeter uas Marconi tau tsim, nws tau siv tsuas yog ntawm lub nkoj-rau-nkoj thiab nkoj-rau-nkoj installation.

wavemeter ua li cas?

Wavemeter, khoom siv rau kev txiav txim siab qhov kev ncua deb ntawm kev ua tiav wavefronts ntawm qhov sib npaug ntawm cov hluav taws xob nthwv dej. Kev txiav txim siab feem ntau ua tsis ncaj, los ntawm kev ntsuas qhov zaus ntawm nthwv dej.

Dab tsi yog wavemeter tubes?

Ib qhov nqus nqus wavemeter yog yooj yim hluav taws xob ntsuas siv los ntsuas qhov zaus ntawm xov tooj cua tsis. … Lub wavemeter muaj ib qho kev hloov kho resonant Circuit Court calibrated nyob rau hauv zaus, nrog ib tug meter los yog lwm yam txhais tau tias los ntsuas qhov voltage los yog tam sim no nyob rau hauv lub circuit.

wavemeter hauv microwave yog dab tsi?

['mī·krə‚wāv 'wāv'mēd·ər] (electromagnetism) Txhua yam khoom siv los ntsuas qhov chaw dawb-qhov wavelengths (lossis zaus) ntawm microwaves; feem ntau yog ua los ntawm cov kab noj hniav resonator uas nws qhov ntev tuaj yeem sib txawv kom txog thaum resonance nrog lub microwaves tiav.

Lub ntsuas ntsuas wavelength ua haujlwm li cas?

Standard wavemeter calibration yog raws li nthwv dej dhau los ntawm qhov chaw dawb ntawm 299, 792, 458 meters ib ob. Qhov no tso cai rau kev txiav txim siab ntawm wavelengths los ntawm kev sib npaug nrog lub wavelength (λ) sib npaug rau kev nthuav tawm nrawm (c) faib los ntawm kev vibration zaus (f), nrog qhov ntsuas kawg hauv hertz.
