1. Into ephakeme engu-2 mm ibekwa ku-10 cm ukusuka engilazini yokukhulisa . Iphuzu eliseduze no-N = 25 cm. Thola ukukhuliswa kwe-angular kanye nokuphakama kwesithombe.
Kwaziwa:
Ukuphakama kwento (h o ) = 2 mm
Iphuzu eliseduze (N) = 25 cm
Ibanga lento (do o ) = 10 cm
Okufunwayo: Ukukhulisa i-Angular (M) kanye nokuphakama kwesithombe (h i )
Isixazululo:
M = N / s
M = 25 cm / 10 cm
M = 2.5
Ukuphakama kwesithombe = 2.5 x 2 mm = 5 mm.
2. Ilensi yobude obuqondile obungu-25 cm isetshenziswa njengengilazi yokukhulisa. Thola (a) ukukhulisa okuqondile lapho iso ligxile endaweni yalo eseduze N = 25 cm (b) ukukhulisa okuqondile lapho iso likhululekile.
Kwaziwa:
Iphuzu eliseduze (N) = 25 cm
Ubude obuqondile bengilazi ekhulisayo (f) = 25 cm
Uphawu lokuhlanganisa lubonisa ukuthi ilensi ilensi ehlanganayo.
Isixazululo:
(a) ukukhulisa okune-angular lapho iso ligxile endaweni yalo eseduze N = 25 cm
M = (N/f) + 1
M = (25 cm / 25 cm) + 1
M = 1 + 1
M = 2 X
Uma ukuphakama kwento kungu-1 cm, ukuphakama kwesithombe kungu-2 x 1 cm = 2 cm.
(b) ukukhulisa i-angular lapho iso likhululekile
M = N / f
M = (25 cm / 25 cm)
M = 1 X
Uma ukuphakama kwento kungu-1 cm, ukuphakama kwesithombe kungu-1 x 1 cm = 1 cm.
3. Into ephakeme engu-1 cm ibekwa phambi kwelensi yobude obuqondile engu-10 cm. Nquma (a) ukuphakama kwesithombe lapho iso ligxile endaweni yalo eseduze N = 25 cm (b) Ukuphakama kwesithombe lapho iso likhululekile.
Kwaziwa:
Ukuphakama kwento (h o ) = 1 cm
Ubude obuqondile (f) = 10 cm
Iphuzu eliseduze (N) = 25 cm
Isixazululo:
(a) Ukuphakama kwesithombe lapho iso ligxile endaweni yalo eseduze N = 25 cm
M = (N/f) + 1
M = (25 cm / 10 cm) + 1
M = 2.5 + 1
M = 3.5 X
Uma ukuphakama kwento kungu-1 cm, ukuphakama kwesithombe kungu-3.5 x 1 cm = 3.5 cm.
(b) Ukuphakama kwesithombe lapho iso likhululekile.
M = N/f
M = 25 cm / 10 cm
M = 2.5 X
Uma ukuphakama kwento kungu-1 cm, ukuphakama kwesithombe kungu-2.5 x 1 cm = 2.5 cm.
4. Ukukhulisa okune-engela lapho iso likhululekile = 5X. Uma kuseduze nephuzu = 25 cm, buyini ubude obuqondile bengilazi yokukhulisa?
Kwaziwa:
Ukuphakama kwento (h o ) = 2 mm
Ukukhulisa i-Angular (M) = 5X
Iphuzu eliseduze (N) = 25 cm
Okufunwayo: Ubude obugxile
Isixazululo:
Ifomula yokukhulisa i-angular lapho iso likhululekile:
M = N/f
5 = 25 cm / f
f = 25 cm / 5
f = 5 cm
Ubude obuqondile bengilazi yokukhulisa = 5 cm.
5. Into ibonwa ngumuntu onengilazi yokukhulisa enobude obuqondile obungu-15 cm. Uma indawo eseduze kwamehlo omuntu = 30 cm, khona-ke nquma ukuthi ingilazi yokukhulisa iyonke ingakanani.
Kwaziwa:
Iphuzu eliseduze leso elivamile (N) = 30 cm
Ubude obuqondile bengilazi ekhulisayo (f) = 15 cm (kanye nophawu lokuthi ingilazi iyahlangana)
Okufunwayo: ukukhuliswa okuphezulu kakhulu
Isixazululo:
Ukukhulisa okuphezulu kwenzeka lapho indawo yeso iphezulu kakhulu. Ukukhulisa okune-angular kwengilazi yokukhulisa kwenzeka lapho indawo yeso iphezulu kakhulu:
M = (N/f) + 1
M = (30 cm / 15 cm) + 1
M = 2 + 1
M = izikhathi ezi-3
6. Ingilazi yokukhulisa enegunya lokukhanya elingama-dioptha angu-20 esetshenziswa ngumuntu onamehlo ajwayelekile angama-25 cm. Uma indawo incane, nquma ukuthi ingakanani i-magnification.
Kwaziwa:
Iphuzu eliseduze neso elivamile (N) = 25 cm
Amandla engilazi yokukhulisa (P) = ama-diopters angu-20
Okufunwayo: Ukukhulisa okuncane
Isixazululo:
Ubude obuqondile bengilazi yokukhulisa:
P = 1/f
20 = 1/f
f = 1/20
f = amamitha angu-0.05
f = 5 cm
Ukwandiswa kwe-angular lapho indawo yokuhlala incane:
M = N / f
M = (25 cm / 5 cm)
M = izikhathi ezi-5
