1. He palena ʻole ka palena ʻole o ka maka maʻamau. ʻO ka lōʻihi o ke kikowaena o ka lens maka he 2.5 kenimika. E hoʻoholo (a) ka mamao o ke kiʻi (b) ka mana o ka lens.
ʻIke ʻia:
ʻO ka lōʻihi o ke kikowaena o ka lens maka (f) = ka mamao ma waena o ka cornea a me ka retina = +2.5 kenimika ( Hōʻike ka hōʻailona plus i ka lens converging ).
ʻO ka mamao o ka mea ( d o ) = palena ʻole
Makemake ʻia : ka mamao o ke kiʻi ( d i )
Lōlā:
(a) ka mamao o ke kiʻi
1/f = 1/ d o + 1/ d i
f = ka lōʻihi o ke kikowaena , d = ka mamao o ka mea , d = ka mamao o ke kiʻi
1/ d i = 1/ f – 1/ d o = 1 / 2.5 – 1 / ~ = 1 / 2.5 – 0
1/ d i = 1 / 2.5
d i = 2.5 kenimika = 0.025 mika
Inā palena ʻole ka mamao o ka mea, ʻo ka mamao o ke kiʻi (d i ) = ka lōʻihi o ke kikowaena (f)
(b) ka mana o ka aniani
P = 1/f = 1/ 0.025 m = 40 I nā mea koho
ʻAʻole maopopo
2. He 25 kenimika ka mamao kokoke o ka maka maʻamau. Ua like ka mamao o ke kiʻi me ka mamao ma waena o ka cornea a me ka retina = 2.5 kenimika. E hoʻoholo (a) ka lōʻihi o ke kikowaena (b) ka mana o ka lens
ʻIke ʻia:
ʻO ka mamao o ka mea ( d o ) = 25 kenimika
ʻO ka mamao o ke kiʻi ( d i ) = 2.5 kenimika
Lōlā:
(a) ka lōʻihi o ke kikowaena (f)
1/f = 1/ d o + 1/ d i
1/f = 1/25 + 1/2,5 = 1/25 + 10/25 = 11/25
f = 2.27 kenimika = 0.0227 m
Hōʻike ka hōʻailona hoʻohui i ka lens converging.
(b) ka mana o ka aniani (P)
P = 1/f = 1/ 0.0227 = 44 I nā mea koho
3. ʻO kekahi o nā mea hana maka he mau maka kanaka . E hoʻoholo i nā ʻano o ke kiʻi i hana ʻia e nā maka kanaka…
A. ʻOiaʻiʻo, kū pololei
B. ʻOiaʻiʻo, hoʻohuli ʻia
C. ʻIkepili, kū pololei
D. Virtual, hoʻohuli ʻia
pāʻoihana
ʻO ke kiko kokoke o ka maka maʻamau he 25 kenimika. ʻO ke kiko kokoke ka kiko kokoke loa i ka maka kahi e kau pono ai kahi mea ma ka retina ma ke kūlana piha. ʻOi aku ka liʻiliʻi o ke anawaena o ka maka kanaka ma mua o 25 kenimika no laila ʻoi aku ka liʻiliʻi o ka lōʻihi o ke aniani o ka maka ma mua o 25 kenimika. No laila, pono e ʻoi aku ka mamao o ka mea (d) ma mua o ka lōʻihi o ke aniani o ka maka (f).
He aniani convex ka aniani maka. No laila, ʻo ke kiʻi i hana ʻia e ka aniani maka he mau ʻano like me ke kiʻi i hana ʻia e ka aniani convex. ʻO nā ʻano o ke kiʻi i hana ʻia e ka aniani maka ke ʻoi aku ka mamao o ka mea (s) ma mua o ka lōʻihi focal (f):
maoli, hoʻohuli ʻia, liʻiliʻi
Pono e kālele ʻia ke kiʻi ma ka retina no ka mea hoʻololi ka retina i nā nalu māmā i mau hōʻailona uila i hoʻouna ʻia i ka lolo. ʻOiai ua hoʻohuli ʻia ke kiʻi, hoʻohuli ka lolo kanaka iā ia i luna i kū pololei nā mea i ʻike ʻia e ka maka.
Ke ʻike ʻoe i kahi lāʻau mai kahi mamao aku, ʻike ʻia ka lāʻau he liʻiliʻi ma mua o kona nui maoli. Kūlike kēia me nā ʻano o ke kiʻi i hoʻemi ʻia.
ʻO ka pane pololei ʻo A.
4. Hiki i ka maka ke ʻike i kahi mea ke kau ʻia ke kiʻi ma ka retina kahi i loaʻa ai nā waiwai o ke kiʻi…
A. ʻAno like, kū pololei, ʻoi aku ka nui
B. Virtual, inverted, liʻiliʻi
C. Maoli, hoʻohuli ʻia, liʻiliʻi
D. Maoli, kū pololei, liʻiliʻi

– He aniani convex ke aniani o ka maka, no laila, ua like nā ʻano o ke kiʻi i hana ʻia e ka aniani maka me nā ʻano o ke kiʻi i hana ʻia e ka aniani convex.
– ʻO ke kiko kokoke o ka maka maʻamau a i ʻole ka mamao kokoke loa e ʻike maopopo ʻia e nā maka he 25 kenimika. He liʻiliʻi loa nā maka o ka maka a ʻoi aku ka liʻiliʻi o ke radius o ke kūlou a me ka lōʻihi o ke kikowaena o ka lens maka ma mua o 25 kenimika. No laila hiki ke hoʻoholo ʻia he ʻoi aku ka mamao o ka mea ma mua o ka lōʻihi o ke kikowaena.
– Inā ʻoi aku ka mamao o ka mea ma mua o ka lōʻihi o ke kikowaena a laila ʻo nā ʻano o ke kiʻi i hana ʻia e ka maka kanaka ma ka retina he ʻoiaʻiʻo, hoʻohuli ʻia, a liʻiliʻi. ʻOiai ua hoʻohuli ʻia ke kiʻi, hoʻohuli ka lolo iā ia i luna i ko mākou ʻike ʻana.
