Tsab xov xwm hais txog Cov Khoom ntawm daim duab uas tsim los ntawm lub lens sib cais
Qhov deb ntawm yam khoom me dua qhov ntev ntawm lub lens concave (do > f)
Raws li kev xam ntawm cov duab tsim los ntawm lub lens concave, nws tuaj yeem xaus lus tias yog tias qhov deb ntawm cov khoom (do) me dua qhov ntev focal (f), ces cov khoom ntawm cov duab yog:
- Virtual txhais tau tias lub teeb tsis hla dhau daim duab
- Ntsug
– Qhov deb ntawm qhov khoom ntawm lub lens concave, qhov me dua ntawm daim duab
- Qhov deb ntawm qhov khoom ntawm lub lens concave, qhov deb ntawm daim duab ntawm lub lens concave
Qhov nrug ntawm yam khoom loj dua qhov ntev ntawm lub lens concave (do > f)
Raws li kev xam ntawm cov duab tsim los ntawm lub lens concave, nws tuaj yeem xaus lus tias yog tias qhov deb ntawm cov khoom (do) loj dua qhov ntev focal (f) ces cov khoom ntawm cov duab yog:
- Virtual txhais tau tias lub teeb tsis hla dhau daim duab
- Ntsug
– Qhov deb ntawm qhov khoom ntawm lub lens concave, qhov me dua ntawm daim duab
- Qhov deb ntawm qhov khoom ntawm lub lens concave, qhov deb ntawm daim duab ntawm lub lens concave
Qhov nrug ntawm cov khoom yog sib npaug rau qhov ntev ntawm lub lens concave (do = f)
Raws li kev xam ntawm cov duab tsim ntawm lub lens concave, tuaj yeem xaus lus tias yog tias qhov deb ntawm cov khoom (do) sib npaug rau qhov ntev focal (f) ntawm lub lens concave ces cov khoom ntawm cov duab yog:
- Virtual txhais tau tias lub teeb tsis hla dhau daim duab
- Ntsug
- Minimized (qhov loj ntawm daim duab ½ npaug ntawm qhov loj ntawm yam khoom)
- Qhov nrug ntawm daim duab me dua qhov nrug ntawm yam khoom (qhov nrug ntawm daim duab me dua ½ npaug ntawm qhov nrug ntawm yam khoom)
- Lo lus nug: Hom duab twg yog tsim los ntawm lub lens diverging? tebIb lub lens sib cais yeej ib txwm tsim cov duab virtual, upright, thiab reduced.
- Lo lus nugQhov chaw ntawm yam khoom cuam tshuam li cas rau qhov loj ntawm daim duab uas tsim los ntawm lub lens diverging? tebTxawm hais tias qhov khoom nyob qhov twg los xij, lub lens sib nrug yuav ib txwm tsim cov duab txo qis.
- Lo lus nugDaim duab uas tsim los ntawm lub lens sib cais nyob qhov twg piv rau lub lens? teb: Daim duab uas tsim los ntawm lub lens diverging nyob rau tib sab ntawm yam khoom, nyob rau hauv qhov ntev ntawm lub lens.
- Lo lus nugQhov ntev ntawm lub lens diverging cuam tshuam li cas rau qhov chaw thiab qhov loj ntawm daim duab? tebQhov ntev ntawm lub lens diverging tsis hloov qhov tseeb tias daim duab yog virtual, upright, thiab txo qis, tab sis lub lens nrog qhov ntev luv dua yuav tsim cov duab me dua ze rau lub lens, piv rau lub lens nrog qhov ntev ntev dua.
- Lo lus nugPuas yog lub lens sib cais puas tuaj yeem tsim tau ib daim duab tiag tiag? tebTsis yog, lub lens sib cais tsis tuaj yeem tsim tau ib daim duab tiag tiag. Nws yeej ib txwm tsim ib daim duab virtual.
- Lo lus nugKev hloov qhov deb ntawm cov khoom cuam tshuam li cas rau qhov chaw ntawm daim duab uas tsim los ntawm lub lens diverging? tebThaum cov khoom txav deb ntawm lub lens, daim duab uas tsim los ntawm lub lens diverging kuj txav deb ntawm lub lens, tab sis nyob hauv qhov ntev focal.
- Lo lus nugYog tias ib yam khoom raug muab tso rau ntawm qhov tsom ntawm lub lens sib cais, daim duab yuav nyob qhov twg? tebRau lub lens uas sib cais, daim duab tseem yuav tsim nyob rau tib sab ntawm yam khoom thiab yuav yog virtual, upright, thiab diminished. Lub tswv yim ntawm kev tso ib yam khoom rau ntawm qhov tsom tsis siv tau tib yam li nws ua rau cov lens sib sau ua ke.
- Lo lus nugPuas yog lub lens diverging tuaj yeem tsim ib daim duab inverted? tebTsis yog, lub lens sib nrug yeej ib txwm tsim ib daim duab ncaj (sab xis-sab saud).
- Lo lus nugCov khoom siv ntawm lub lens (iav, yas, thiab lwm yam) puas cuam tshuam rau cov yam ntxwv ntawm daim duab uas tsim los ntawm lub lens diverging? tebCov khoom siv ntawm lub lens tuaj yeem cuam tshuam rau qhov ntev ntawm lub lens vim muaj cov ntsuas refractive sib txawv, tab sis nws yuav tsis hloov cov yam ntxwv tseem ceeb ntawm daim duab uas tsim los ntawm lub lens diverging. Daim duab yuav tseem virtual, upright, thiab reduced.
-
Lo lus nug : Yog tias lub lens sib cais muaj qhov ntev focal tsis zoo, qhov no cuam tshuam li cas rau kev tsim thiab cov khoom ntawm daim duab? Teb : Qhov ntev focal tsis zoo ntawm lub lens sib cais qhia txog kev coj ntawm lub teeb khoov, tab sis nws tsis hloov cov khoom ntawm daim duab. Daim duab tseem yuav virtual, ncaj, thiab txo qis.
