Frequency yog qhov ntsuas ntawm tus naj npawb ntawm nthwv dej ib pliag. Wavenumber yog qhov sib piv ntawm lub wavelength sib npaug los ntawm qhov tas li Txawm tias lawv zoo ib yam, qhov txawv yog qhov wavenumber tsis muaj dab tsi cuam tshuam nrog qhov nrawm ntawm nthwv dej- wavenumber ntsuas hauv cm^- 1, uas tsis suav nrog lub sijhawm.
wavenumber cuam tshuam li cas rau zaus?
Wavenumber, tseem hu ua yoj tus lej, ib chav ntawm zaus, feem ntau siv hauv atomic, molecular, thiab nuclear spectroscopy, sib npaug rau qhov tseeb zaus faib los ntawm kev ceev ntawm nthwv dej thiab yog li sib npaug rau cov nthwv dej hauv ib chav nyob deb. Tus lej no hu ua wavenumber ntawm kab spectrum.…
Puas yog wavelength thiab wavenumber tib yam?
Wavelength yog qhov kev ncua deb ntawm ob lub ntsiab lus sib law liag uas nyob rau tib theem. Wavenumber yog tus naj npawb ntawm wavelengths nyob rau hauv ib qho kev ncua deb raws li kev nthuav tawm ntawm nthwv dej.
Yuav ua li cas koj xam wavenumber?
Tus naj npawb nthwv dej rau thaj chaw EM yog sib npaug rau 2 pi muab faib los ntawm lub wavelength hauv meters (Hauv qee qhov kev siv, nws txhais tau tias yog qhov sib txuam ntawm lub wavelength hauv meters; Nyob rau hauv lwm yam lus, nws yog txhais raws li reciprocal ntawm lub wavelength nyob rau hauv centimeters.) Raws li lub wavelength loj hlob luv, tus nthwv dej yuav loj dua.
Puas yog wavenumber ncaj qha proportional rau zaus?
Rau hluav taws xob hluav taws xob hauv lub tshuab nqus tsev, wavenumber yog ncaj qha proportional rau zaus thiab rau photon zog. Vim li no, wavenumbers yog siv los ua ib chav tsev yooj yim ntawm lub zog hauv spectroscopy.
