Txhua yam khoom siv hauv lub ntiaj teb no yog tsim los ntawm cov atoms. Cov atoms yog tsim los ntawm protons, neutrons, thiab electrons. Proton muaj hluav taws xob zoo; cov electrons muaj hluav taws xob tsis zoo, neutrons tsis muaj hluav taws xob. Hauv lub atom, muaj qee cov electrons, protons, thiab neutrons. Yog tias tus lej ntawm cov electrons sib npaug rau tus lej ntawm cov protons, tag nrho cov hluav taws xob ntawm lub atom yog xoom. Cov atoms zoo li no yog hluav taws xob nruab nrab. Yog tias tus lej ntawm cov electrons ntau dua tus lej ntawm cov protons, ces lub atom yuav raug hluav taws xob tsis zoo. Yog tias tus lej ntawm cov electrons tsawg dua tus lej ntawm cov protons, ces lub atom yuav raug hluav taws xob zoo.

Vim li cas cov yas thiaj li tiv thaiv cov yas tab sis nyiam cov iav? Yog tias koj txhuam cov yas rau ntawm cov plaub hau qhuav thiab coj cov yas mus rau ntawm cov ntawv me me, cov yas rub cov ntawv. Vim li cas cov yas kuj tseem rub cov ntawv uas tsis tau txhuam nrog lwm yam khoom? Koj yuav nkag siab thiab tuaj yeem piav qhia txog cov laj thawj rau qhov xwm txheej uas cov iav, yas, daim ntawv lossis lwm yam khoom ntsib raws li tau tshuaj xyuas saum toj no tom qab koj kawm txog cov nqi hluav taws xob thiab nkag siab txog cov kev tshuaj xyuas hauv qab no.

Cov yas uas raug txhuam nrog cov plaub hau rub iav txhuam nrog daim ntaub. Cov yas thiab iav yog qhov zoo nkauj, yog li cov yas thiab iav muaj cov nqi hluav taws xob sib txawv . Yog tias ib yam khoom tawm tsam yas tab sis rub iav, nws muaj qhov them zoo ib yam li qhov them ntawm iav. Ntawm qhov tod tes, yog tias ib yam khoom tawm tsam iav tab sis rub yas, nws muaj qhov them zoo ib yam li qhov them ntawm yas.

Thov saib ib yam khoom uas nyob ib puag ncig koj. Yog tias koj rhuav tshem ib yam khoom, piv txwv li, nws yog pob zeb, lub pob zeb yuav raug faib ua tej daim me me. Yog tias ib feem ntawm lub pob zeb raug rhuav tshem dua, cov pob zeb yuav hloov mus ua tej daim me me. Yuav ua li cas yog tias lub pob zeb raug rhuav tshem dua? Tau kawg, lub pob zeb me dua. Puas yog pob zeb raug rhuav tshem ua tej daim me me mus rau tej daim tsis kawg? Qhov tseeb qhia tau hais tias ib yam khoom raug faib ua tej daim me me yuav tuaj txog rau qhov chaw uas qhov me tshaj plaws ntawm yam khoom tsis tuaj yeem faib ua tej daim me me. Qhov me tshaj plaws ntawm yam khoom uas tsis tuaj yeem faib tau hu ua atom. Yog li, atoms yog qhov me tshaj plaws ntawm txhua yam khoom siv hauv lub ntiaj teb.

Cov khoom ntawm lub koob yees duab

Ib lub koob yees duab yooj yim muaj lub lens convex, diaphragm, shutter, thiab zaj duab xis.

Cov iav convex ua haujlwm los tsim cov duab tiag tiag thiab cov duab tig rov qab rau ntawm zaj duab xis. Tsis zoo li lub lens ntawm lub qhov muag uas muaj qhov ntev focal uas tuaj yeem hloov pauv, lub koob yees duab lens muaj qhov ntev focal uas tsis tuaj yeem hloov pauv. Lub koob yees duab lens yog lub lens convex, tsis yog lub lens concave vim tias cov duab tsim los ntawm lub lens concave yeej ib txwm yog virtual. Hloov chaw, cov duab tsim los ntawm lub lens convex yog qhov tseeb thaum qhov deb ntawm cov khoom loj dua qhov ntev focal. Ib daim duab tiag tiag yog ib daim duab uas muaj nyob vim tias daim duab no tuaj yeem kaw rau ntawm zaj duab xis. Ntawm qhov tsis sib xws, daim duab virtual yog daim duab cuav yog li cov duab tsis tuaj yeem kaw rau ntawm zaj duab xis. Qhov chaw ntawm cov duab tiag tiag thiab cov duab tig rov qab uas tsim los ntawm lub lens convex sib xws nrog qhov chaw ntawm zaj duab xis.

Lub kaum sab xis txiav txim qhov loj ntawm daim duab ntawm yam khoom uas tsim nyob rau ntawm lub retina. Raws li pom hauv daim duab, qhov deb ntawm yam khoom ntawm lub qhov muag deb npaum li cas, lub kaum sab xis me dua thiab yog li ntawd qhov loj ntawm daim duab uas tsim nyob rau ntawm lub retina kuj me dua.

Lub tsom iav saib hnub qub yooj yim muaj ob lub lens convex; txhua lub hu ua lub lens objective thiab lub lens ocular. Lub lens objective muaj qhov deb ntawm lub qhov muag ntau dua, thaum lub lens ocular muaj qhov deb ze dua rau lub qhov muag. Lub lens objective ua haujlwm coj cov duab los ze rau lub lens ocular, yog li lub kaum sab xis loj dua. Lub lens ocular ua haujlwm kom lub kaum sab xis nce kom qhov loj ntawm cov duab tsim ntawm retina loj dua.

Raws li tau piav qhia hauv zaj lus qhia loupe (lub iav loj), ib yam khoom zoo li me me thaum saib ntawm qhov deb heev thiab zoo nkauj thaum saib ze. Qhov sib txawv ntawm qhov loj ntawm yam khoom uas lub qhov muag pom yog vim qhov sib txawv ntawm lub kaum sab xis ntawm lub qhov muag thiab yam khoom. Thaum ib yam khoom nyob deb ntawm lub qhov muag heev, lub kaum sab xis ntawm lub qhov muag thiab yam khoom me dua yog li daim duab uas tsim rau ntawm retina ntawm lub qhov muag kuj me dua. Ntawm qhov tod tes, thaum yam khoom nyob ze rau lub qhov muag, lub kaum sab xis ntawm lub qhov muag thiab yam khoom loj dua yog li daim duab uas tsim rau ntawm retina ntawm lub qhov muag kuj tseem ceeb dua. Qhov nyob ze rau lub qhov muag, lub kaum sab xis ntawm lub qhov muag thiab yam khoom siab dua, yog li daim duab uas tsim rau ntawm retina kuj loj dua. Nco ntsoov tias lub qhov muag tib neeg feem ntau muaj qhov ze yog 25 cm yog li qhov deb ntawm lub qhov muag thiab yam khoom yuav tsum tsis txhob me dua 25 cm. Nws tuaj yeem xaus lus tias lub kaum sab xis ntawm lub qhov muag ib txwm ntawm tib neeg thiab yam khoom yog qhov siab tshaj plaws thaum qhov deb ntawm lub qhov muag thiab yam khoom yog 25 cm.
