Ingxoxo

Ake sithi ibanga lendawo yokugxila noma ubude be-focal (f) = 20 cm kanye nebanga lento (s) = 10 cm, njengoba kuboniswe esithombeni esingezansi.

a) Ibanga lesithunzi

1/f = 1/s + 1/s'

1/20 = 1/10 + 1/s'

1/20 – 1/10 = 1/s'

1/20 – 2/20 = 1/s'

-1/20 = 1/s'

s' = -20 cm

Ibanga elibi lesithunzi lisho ukuthi isithunzi singokoqobo. Isithunzi singokoqobo ngoba akukho ukukhanya okudlula kuso. Lokhu kuboniswa umugqa onamachashazi esithombeni.

b) Ukukhulisa isithombe

M = -s'/s = -(-20)/10 = 20/10 = izikhathi ezingu-2

Ukukhulisa isithombe kahle kusho ukuthi isithombe siqondile. Isithombe sikhuliswe izikhathi ezimbili.

Izakhiwo zezithunzi ezisekelwe esithombeni kanye nemiphumela yokubala engenhla yilezi:

1. Kukhuliswe izikhathi ezimbili

Imibuzo Yefiziksi Yezivivinyo Zikazwelonke Zesikole Samabanga Aphezulu/Isikole Samabanga Aphezulu Sokufundela Umsebenzi

Imibuzo eyisibonelo mayelana nezinsimbi zamehlo ezibonakalayo
Umuntu onamehlo ajwayelekile uqala ukubona into eqhele ngamamitha angu-500. Ngemva kwemizuzwana embalwa umuntu ubona into eqhele ngamamitha angu-1. Ibanga eliphakathi kwe-cornea ne-retina mata kubhekwa njengebanga lesithunzi, elingaba ngu-2,5 cm. Bala:
(a) Ubude be-focal kanye namandla e-eyepiece uma ugxila entweni eqhele ngamamitha angu-500
(b) Ubude be-focal kanye namandla e-eyepiece uma ugxila entweni eqhele ngemitha elilodwa
(c) Ushintsho kubude obuqondile be-eyepiece lapho kugxilwa amaswishi kusuka kumamitha angu-500 kuya kumitha eli-1.
Ingxoxo
Kuyaziwa ukuthi:
Ibanga lento 1 (s)₁) = imitha eli-500 = 50.000 cm
Ibanga lento 2 (s)₂) = imitha eli-1 = 100 cm
Ibanga lesithunzi (s') = 2,5 cm
Impendulo:
(a) Ubude be-focal kanye namandla e-lens yeso lapho iso ligxila entweni eqhele ngamamitha angu-500
Ubude be-focal (f) be-eyepiece bubalwa kusetshenziswa ifomula yelensi eqondile :
1/f₁ = 1/s₁ + 1/s' = 1/50.000 + 1/2,5 = 1/50.000 + 20.000/50.000 = 20.001/50.000
f₁ = 50.000/20.001 = 2,499875 cm
f₁ = 0,02499875 imitha
Amandla ngelensi yeso:
P₁ = 1/f₁ = 1/0,02499875 = 40,0 Diopters

(b) Ubude be-focal kanye namandla e-lens yeso lapho iso ligxila entweni eqhele ngemitha elilodwa
Ubude be-focal (f) be-eyepiece:
1/f₂ = 1/s₂ + 1/s' = 1/100 + 1/2,5 = 1/100 + 40/100 = 41/100
f₂ = 100/41 = 2,439024 cm
f₂ = 0,02439024 imitha
Amandla ngelensi yeso:
P₂ = 1/f₂ = 1/0,02439024 = 41,0 Diopters

(c) Ushintsho kubude be-focal kanye namandla e-lens yeso lapho kushintsha ukugxila kusuka kumamitha angu-500 kuya kumitha eli-1.
Ushintsho kubude be-focal lens yeso = f₁ - f₂ = 0,02499875 – 0,02439024 = 0,00060851 amamitha
Ushintsho emandleni elensi yeso = 41,0 – 40,0 = 1,0 Diopters

Ngokusekelwe engxoxweni yemibuzo engenhla, kungaphethwa ngokuthi:
– Ubude be-focal lens yeso bukhulu uma iso libona izinto zikude kanti ubude be-focal lens yeso buncane uma iso libona izinto zikude.
– Amandla ngelensi yeso makhulu uma iso libheka into eseduze, kanti amandla ngelensi yeso mancane uma iso libheka into ekude. Ngakho-ke, lapho into iseduze, amandla ngelensi yeso makhulu.
