Nyob rau hauv physics, lub wavelength yog lub sij hawm spatial ntawm ib ntus nthwv dej-qhov kev ncua deb uas cov nthwv dej cov duab rov ua dua.
txhais tau li cas los ntawm wavelength range?
Definition: Wavelength tuaj yeem txhais tau tias qhov kev ncua deb ntawm ob lub crests los yog troughs ntawm nthwv dej. Nws yog ntsuas nyob rau hauv cov kev taw qhia ntawm yoj.
thaj tsam spectral yog dab tsi?
spectral band lossis spectral cheeb tsam: Ib qho zoo-txhais, nruam wavelength ntau nyob rau hauv lub spectrum ntawm reflected los yog radiated electromagnetic zog. Liab, ntsuab, thiab xiav yog tag nrho cov cheeb tsam spectral nyob rau hauv ib feem ntawm lub spectrum uas pom rau tib neeg li lub teeb.
Dab tsi yog qhov pub dawb spectral ntau hauv optics?
Free spectral range (FSR) yog qhov sib nrug ntawm qhov chaw kho qhov muag lossis wavelength ntawm ob qhov kev cuam tshuam los yog kis tau qhov muag pom kev siv maxima lossis minima ntawm interferometer lossis diffractive optical element, tab sis hloov qee zaum sawv cev los ntawm cov ntawv FSR xwb.
Koj pom qhov spectral dawb li cas?
