Indlela nemithombo
I-optics yangaphansi kwamanzi nokwakhiwa kwamehlo ezinhlanzi okukaliwe: yimuphi umbala wesiyengo uhlobo oluthile lwenhlanzi olukwazi ngempela ukuwubona ekujuleni okuthile, emanzini athile, nokuthi ukude kangakanani. Yonke inombolo inomthombo.
Funda lokhu ngaphambi kokuthemba inombolo
Lolu hlelo lulingisa ifiziksi yokukhanya nomehluko ngaphansi kwamanzi. Alulingisi ukuziphatha kwenhlanzi futhi alukwazi ukukuthembisa ukubamba. Lokho olukutshela khona ukuthi isiyengo sivela kangakanani emanzini — okuyinto ekhona ngempela nelinganisekayo, futhi yiyo enquma ukuthi inhlanzi ingakwazi yini nokwehlukanisa isiyengo sakho nesizinda.
Indlela
Izinhlobo zamanzi ze-optics zikaJerlov nemodeli ye-CDOM/udaka/i-chlorophyll yamanzi amtoti; umthetho kaBeer no-Lambert ngokwehla komugqa; ukudluliswa komehluko kukaDuntley (1963) kubalwa nokukhanya okumboza okubuyiselwe emuva; izifanekiso zepigimenti yokubona zikaGovardovskii (2000) ezisuselwa kumakhoni akaliwe e-lambda-max; ibanga lokubona lika-Aksnes no-Utne (1997).
Lokho lawa manzi akudlulisayo
I-K_d ukuncipha okusabalele kokukhanya okwehlayo; i-c ukuncipha komsebe ngokomugqa wokubuka. Ukuxuba lokhu kokubili yiphutha elivamile kulo mkhakha.
Kukaliwe kulolu hlobo
I-microspectrophotometry eqondile, i-ERG noma ukuzwela kwe-spectrum okuhlolwe ngokuziphatha kwalolu hlobo.
Kukaliwe esihlotsheni esiseduze
Alukho ukukala okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe esihlotsheni sohlobo olufanayo olunendlela yokudla efanayo.
Kukaliwe emndenini ofanayo
Alukho ukukala okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ezingeni lomndeni — kuthembekile ekusho ukuthi yimuphi umkhawulo we-spectrum, hhayi ekuhleleni okucijile phakathi kwemibala eseduze.
Ayikho idatha ye-spectrum — kulinganiselwe
Ayitholakalanga idatha eqondile ye-spectrum. Iziqongo zamakhoni yizilinganiso ezisuselwa ekukhanyeni kwendawo ehlala kuyo nasezihlotsheni zayo, akulona ukukala. Themba imiphumela yamanzi neyokujula kakhulu kunokuhleleka kwemibala.
I-UV ayikwazi ukuboniswa
Lolu hlobo lunekhoni ye-UV, kanti isikrini sefoni asikwazi ukukhipha i-ultraviolet. Isiteshi se-UV sidwetshwe ngombala ongewona, njengoba sisho. Qaphela futhi ukuthi i-UV imunceka ngokushesha ngaphansi kwamanzi futhi inyamalala kungakahambi namasentimitha emanzini anetanini.
