Reflecting Telescopes vs. Refracting Telescopes . A refracting tsom iav raj ( refractor ) siv lo ntsiab muag los sib sau ua ke thiab tsom teeb, thaum a tsom iav tsom iav (reflector) siv daim iav. Cov refractor tsom iav sib sau ua ke ntau dua ntawm lub teeb rau hauv lub lens dua li tuaj yeem sib sau nrog qhov muag liab qab.

Tsuas yog li ntawd, qhov txawv ntawm kev xav thiab refracting telescope yog dab tsi?

Lub ntsiab tivthaiv nyob rau hauv ib tug reflecting telescope yog ib daim iav uas lub teeb yuav thaws tawm thiab ces tsom mus rau ib qho chaw me me. Piv txwv li, a refracting tsom iav raj siv lo ntsiab muag uas tsom lub teeb thaum nws mus rau lwm qhov kawg. Lwm qhov txiaj ntsig tseem ceeb ntawm reflecting telescopes yog qhov loj npaum li cas koj tuaj yeem ua rau lawv.

Kuj Paub, dab tsi yog qhov zoo ntawm lub tsom iav tsom iav tshaj qhov tsom iav tsom iav? Reflecting telescopes muaj ntau Qhov zoo tshaj ntawm refracting telescopes . Cov iav tsis ua rau chromatic aberration thiab lawv yooj yim dua thiab pheej yig dua los tsim loj. Cov kuj tseem yooj yim dua rau mount vim tias lub nraub qaum ntawm daim iav tuaj yeem siv los txuas rau lub mount.

Hais txog qhov no, ob qho tib si reflecting thiab refracting telescopes tsim los ua dab tsi?

Refracting telescopes siv lo ntsiab muag kom pom lub teeb, thiab reflecting telescopes siv daim iav. Kuv mam tham ua ntej refracting cov. Refracting telescopes ua hauj lwm los ntawm kev siv ob lo ntsiab muag los tsom lub teeb thiab ua nws zoo li qhov khoom nyob ze koj dua li qhov tiag tiag. Ob leeg lo ntsiab muag yog nyob rau hauv cov duab uas hu ua 'convex'.

Cov astronomers puas siv cov tsom iav los yog tsom iav?

Astronomers siv telescopes los sib sau ua ke lub teeb, daws cov ntsiab lus zoo, thiab nthuav cov duab. Reflecting telescopes siv daim iav tsom lub teeb thiab tsis tshua kim dua refracting telescopes ntawm tib txoj kab uas hla. Tsis tas li ntawd, reflecting telescopes ua tsis raug kev txom nyem los ntawm chromatic aberration.
