Cov iav tsom iav muaj qhov nkhaus nkhaus nrog qhov nruab nrab ntawm qhov nkhaus sib npaug ntawm txhua qhov taw qhia ntawm daim iav saum npoo. Ib yam khoom dhau ntawm qhov nruab nrab ntawm qhov curvature tsim ib daim duab tiag thiab thim rov qab ntawm lub focal point thiab qhov nruab nrab ntawm curvature.
Qhov chaw ntawm curvature ntawm daim iav concave yog dab tsi?
Qhov chaw ntawm curvature ntawm ib daim iav kheej kheej nyob ntawm center sphere. Daim iav spherical uas yog polished los ntawm sab nraud xws li nws yog reflecting los ntawm sab hauv yog hu ua concave daim iav. Qhov chaw ntawm curvature ntawm daim iav convex nyob tom qab daim iav.
Thaum ib qho khoom tso rau ntawm qhov chaw ntawm curvature ntawm daim iav concave cov duab yuav nyob?
Ib yam khoom tso rau ntawm qhov chaw ntawm qhov curvature tshwm sim los ntawm kev tsim cov duab tiag tiag, rov qab nyob ntawm ntawm tib qhov chaw thiab qhov loj tib yam li cov khoom.
Yuav ua li cas thaum ib yam khoom muab tso rau ntawm qhov chaw ntawm curvature ntawm daim iav concave?
Yog li ntawd, daim duab yuav hloov pauv thiab loj tib yam li cov khoom. Cov duab zoo li no yog hu ua cov duab tiag tiag vim tias lawv tau tsim los ntawm qhov sib koom ua ke ntawm cov teeb pom kev zoo ntawm cov duab qhov chaw. Cov duab tiag tiag yeej ib txwm tsim ntawm tib sab ntawm daim iav raws li cov khoom.
Thaum ib qho khoom muab tso rau ntawm qhov chaw ntawm curvature ntawm daim iav concave dab tsi yog tus yam ntxwv ntawm daim duab?
Cov yam ntxwv ntawm daim duab tsim los ntawm daim iav concave rau cov khoom tso rau ntawm qhov chaw ntawm curvature yog:
- Txoj Haujlwm: Ntawm qhov chaw ntawm qhov nkhaus ntawm tib sab.
- Size: tib yam li qhov loj ntawm qhov khoom.
- Nature: Real, inverted.
