DEFINITION NTAWM PARTS :? Center ntawm Curvature - qhov taw tes nyob rau hauv nruab nrab ntawm lub kheej kheej los ntawm uas lub iav ua hlais. ? Focal Point/Focus - lub ntsiab lus ntawm lub vertex thiab qhov nruab nrab ntawm curvature . ? Vertex - lub ntsiab lus ntawm lub iav nto qhov twg tus thawj axis ntsib lub iav.

Ib yam li ntawd, qhov txawv ntawm daim iav yog dab tsi?

Tsev Daim iav Hom | Yuav siv lawv li cas kom zoo

  • Plane Mirror - Cov no yog cov iav tiaj tus uas muaj kev cuam tshuam cov duab hauv lawv qhov kev faib ua feem, thim rov qab los ntawm sab laug mus rau sab xis.
  • Concave Mirror - Concave mirrors yog cov iav kheej kheej uas nkhaus sab hauv zoo li rab diav.
  • Convex Mirror - Convex mirrors kuj yog tsom iav.

Tsis tas li ntawd, cov duab tsim nyob rau hauv daim iav nkhaus li cas? Peb twb paub tias ib duab yog tsim -- los yog ib yam dab tsi yog "pom" -- thaum lub teeb rays diverge los ntawm ib tug taw tes. Ntawm no, lub teeb rays uas pib ntawm point O ntawm cov khoom ntaus a nkhaus daim iav thiab tau xav txog qhov ntawd yog li lawv tau sib sau ua ke rau taw tes kuv thiab tom qab ntawd diverge los ntawm taw tes kuv thaum lawv txuas ntxiv mus.

Qhov thib ob, koj hu li cas iav uas zoo li tsim ib ntu ntawm ib sab?

Xws li iav yog hu ua spherical mirrors . Ob hom ntawm spherical iav yog qhia nyob rau hauv daim duab ntawm sab xis. Spherical iav tuaj yeem xav tias yog ib ib feem ntawm ib tug kheej kheej uas tau hlais tseg thiab ces silvered ntawm ib sab rau daim ntawv ib tug reflecting nto.

Tus ncej ntawm daim iav yog dab tsi?

Qhov chaw uas tus thawj axis tho qhov iav yog hu ua ncej ntawm iav . Sib piv qhov no nrog cov ncej ntawm lub ntiaj teb, qhov chaw uas lub tswv yim axis ntawm kev sib hloov pierces lub literal nto ntawm lub ntiaj teb spherical.
