Lus Txhais Ntawm Cov iav Magnifying

Lub iav tsom iav yog ib qho yooj yim pom cov khoom siv kho qhov muag siv los soj ntsuam cov ntsiab lus me me ntawm cov khoom. Nws yog convergent lens nrog ib tug focal ntev npaum li cas me dua qhov pom kev deb ntawm lub qhov muag. Qhov loj ntawm daim duab ntawm ib yam khoom ntawm lub retina ntawm tib neeg lub qhov muag yog proportional rau lub kaum sab xis ntawm qhov pom (Lub kaum sab xis ntawm qhov pom) ntawm cov khoom rau lub qhov muag.

Magnifying iav tseem hu ua daim iav hluav taws. Cov cuab yeej kho qhov muag yooj yim kom tau txais daim duab loj dua. Nws feem ntau muaj lub lens convex, ncej thiab kov. Thaum siv, cov khoom tau muab tso rau ze rau sab nraum qab ntawm lub lens (hauv qhov focal ntev), koj tuaj yeem pom qhov kev nthuav dav ntsug ntawm cov duab virtual, uas yuav pab kom paub qhov txawv ntawm cov ntsiab lus, thiab feem ntau siv los saib cov qauv, kos duab, tsis zoo. , cov duab, cov ntawv luam yeeb yaj kiab, thiab lwm yam Raws li qhov curvature thiab qhov sib txawv refractive index ntawm iav siv, muaj 10X, 20X 30X ntawm amplification.
