Qhov sib txawv tseem ceeb ntawm prism spectra thiab grating spectrum yog tias nyob rau hauv prism spectra, lub spectrum yog tsim los ntawm dispersion ntawm lub teeb, whereas nyob rau hauv grating spectra, lub spectrum yog tsim vim lub diffraction ntawm lub teeb.
A spectrum yog ib pawg lossis cov xim uas tsim los ntawm kev sib cais ntawm cov khoom ntawm lub teeb raws li qhov sib txawv ntawm qhov sib txawv thiab lawv cov wavelengths. Prism spectra thiab grating spectra yog ob hom spectra uas txawv ntawm ib leeg, feem ntau nyob rau hauv txoj kev tsim.
Prism Spectra yog dab tsi?
Prism spectra yog qhov txuas ntxiv uas peb tuaj yeem tau txais kev siv prism. Lub prism yog cov cuab yeej pob tshab uas yog daim duab peb sab thiab muaj qhov nruab nrab refracting uas tuaj yeem ua rau lub teeb pom kev. Nws muaj lub hauv paus thiab lub apex, thiab nws lub apical lub kaum ntse ntse txiav txim siab lub zog diprotic ntawm cov khoom. Thaum lub teeb hla lub prism, lub teeb tau tawg los ntawm nws, muab lub prism spectrum.
Pom pom lub teeb feem ntau yog lub teeb dawb, uas muaj cov khoom sib sau ua ke. Feem ntau, peb tuaj yeem saib cov xim no thaum lub teeb dhau los ntawm daim duab peb sab prism. Qhov no yog vim lub teeb dawb cais rau hauv nws cov xim xim thaum lub teeb hla lub prism. Cov xim uas peb tuaj yeem pom yog liab, txiv kab ntxwv, daj, ntsuab, xiav, thiab violet. Feem ntau, cov txheej txheem kev sib cais xim no hu ua dispersion.
Kev faib tawm ntawm cov xim hauv lub teeb tuaj yeem piav qhia raws li qhov sib txawv thiab qhov sib txawv ntawm txhua qhov xim. Cov sib txawv ntawm lub teeb no zoo li khoov ntawm qhov sib txawv raws li lub teeb hla dhau lub prism.
thaum xav txog cov ntaub ntawv ntawm prism, cov khoom sib txawv muaj qhov sib txawv ntawm cov khoom siv kom qeeb lub teeb thaum lub teeb dhau los ntawm cov khoom ntawd). Thaum lub teeb dhau los ntawm cov khoom pob tshab, nws nyiam cuam tshuam nrog cov atoms ntawm cov khoom. Yog hais tias qhov zaus ntawm lub teeb nthwv dej sib piv nrog cov zaus resonance ntawm cov electrons hauv atoms, lub teeb yog absorbed los ntawm lub atom. Lub teeb unabsorbed los ntawm lub prism, uas muab peb lub prism spectrum.
Grating Spectra yog dab tsi?
Grating spectra yog qhov spectra peb tuaj yeem tau txais los ntawm grating prisms. Cov spectra no tshwm sim raws li kab spectra, thiab lawv tsim vim lub teeb diffraction. Cov txheej txheem no tseem ceeb heev hauv kev txheeb xyuas cov teeb pom kev zoo. Ib qho grating spectrum muaj ntau qhov sib npaug ntawm qhov sib npaug sib npaug. Lub hauv paus tshwm sim ntawm lub hauv paus ntsiab lus ua hauj lwm ntawm lub grating spectra yog lub teeb diffraction. Muaj qhov chaw nruab nrab ntawm cov kab ntawm cov spectrum no uas tshwm sim li slits; cov slits no cuam tshuam lub teeb nthwv dej, tsim ntau cov kab sib txawv uas tuaj yeem cuam tshuam los tsim cov spectrum.
Ib grating prism lossis grism tuaj yeem piav qhia raws li kev sib xyaw ntawm prism thiab grating system uas tau teeb tsa nrog rau cov prims, uas tso cai rau lub teeb ntawm ib qho kev xaiv wavelength kom dhau los ntawm prism ncaj qha. Qhov system prism no muaj qhov zoo ntawm kev tso cai rau ib lub koob yees duab los siv rau cov duab thiab cov kev xav tau spectroscopic yam tsis tau tshem tawm lossis hloov lub prism.
Qhov txawv ntawm Prism Spectra thiab Grating Spectra yog dab tsi?
Prism spectra thiab grating spectra yog ob hom spectra uas txawv ntawm ib leeg, feem ntau yog nyob rau hauv txoj kev tsim. Qhov sib txawv tseem ceeb ntawm prism spectra thiab grating spectrum yog tias, nyob rau hauv prism spectrum, lub spectrum yog tsim los ntawm dispersion ntawm lub teeb, whereas nyob rau hauv grating spectrum, lub spectrum yog tsim vim lub diffraction ntawm lub teeb. Ntxiv mus, prism spectrum muab ib qho kev nruam spectrum, whereas grating spectra muab ib kab spectrum.
Cov hauv qab no infographic qhia txog qhov sib txawv ntawm prism spectra thiab grating spectra hauv daim ntawv tabular.
Summary – Prism Spectra vs Grating Spectra
Prism spectra thiab grating spectra yog ob hom spectra uas txawv ntawm ib leeg, feem ntau yog nyob rau hauv txoj kev tsim. Qhov sib txawv tseem ceeb ntawm prism spectra thiab grating spectrum yog tias, nyob rau hauv prism spectra, lub spectrum yog tsim los ntawm dispersion ntawm lub teeb, whereas nyob rau hauv grating spectrum, lub spectrum yog tsim vim lub diffraction ntawm lub teeb.
