7 Ngā Tauira o ngā Pātai e Whakamahi ana i te Loupe, i te Karāhe Whakanui rānei
1. Ko te teitei o tētahi mea ina tirohia tika mai i te pūwāhi tata o te kanohi noa he 2 mm. Kātahi ka tirohia te mea mā te whakamahi i tētahi karāhe whakanui . Mena he 10 cm te tawhiti o te mea i mua i te karāhe whakanui, he aha te teitei o te ahua o te mea i hangaia e te karāhe whakanui? Ko te pūwāhi tata o te kanohi noa he 25 cm.
Kōrero
E mōhiotia ana:
Teitei o te mea (h) = 2 mm
Te pūwāhi tata o te kanohi noa (N) = 25 cm
Te tawhiti o te mea (s) = 10 cm
I pātaihia: Te koki whakanui o te loupe (M)
2 Ngā tauira pātai mō ngā taputapu whatu kāmera
1. Ko te roa arotahi o tētahi kāmera anaro kotahi-arotahi he 10 cm. I te tīmatanga, ka whakaritea te kāmera ki te whakaahua i tētahi mea i te mutunga kore. Ki te hiahia tētahi ki te whakamahi i te kāmera ki te whakaahua i tētahi mea e 5 mita te tawhiti, tatauhia:
(a) Te tawhiti i waenganui i te kiriata me te arotahi ina whakaritea te kāmera ki te whakaahua i tētahi mea i te mutunga kore,
(b) Te tawhiti i waenganui i te kiriata me te arotahi ina whakaritea te kāmera ki te tango whakaahua i tētahi mea e 100 mita te tawhiti,
(c) Hurihia te tūnga o te arotahi mai i te tautuhinga mutunga kore ki te tautuhinga 100 mita. Kua nekehia te arotahi ki tawhiti atu i te kiriata, ki te tata atu rānei ki te kiriata?

Kōrero
Ngā Wāhanga Kāmera
He kāmera māmā ngā mea kei roto karāhe kōpiko, te diaphragm o te kanohi, te arai me te kiriata.
Karāhe kōpiko He mahi hei hanga whakaahua tūturu, whakaahua huripokitia hoki i runga i te kiriata. He rerekē ki te karu tirohanga, he rerekē te roa arotahi, he pumau te roa arotahi o te karu tirohanga kāmera. He karu tirohanga pūkohu te karu tirohanga kāmera, ehara i te karu tirohanga kōpiko, nā te mea he mariko tonu te whakaahua i hangaia e te karu tirohanga kōpiko. I tetahi atu taha, he tūturu te whakaahua i hangaia e te karu tirohanga pūkohu ina nui ake te tawhiti o te mea i te roa arotahi. Ko te whakaahua tūturu he whakaahua e tino ora ana, nō reira ka taea te tuhi i tēnei whakaahua ki runga i te kiriata. I tetahi atu taha, he whakaahua teka te whakaahua mariko, nō reira kāore e taea te tuhi ki runga i te kiriata. Ka ōrite te tūranga o te whakaahua tūturu me te whakaahua huripokitia i hangaia e te karu tirohanga pūkohu ki te tūranga o te kiriata.
Te whakamāramatanga o te karu tirohanga whenua (ngā karu tirotiro)
Ko te karu tirohanga whenua, ko te karu tirohanga whenua rānei, he taputapu whatu e whakamahia ana hei tirotiro i ngā mea tawhiti kei runga i te mata o te Ao. Ka whakamahia ngā karu tirohanga whenua hei tirotiro i ngā mea kei runga i te mata o te Ao, nō reira me poutū te ahua whakamutunga e puta mai ana i te karu tirohanga kia kore ai e uaua te tirotiro. He rerekē tēnei i ngā karu tirohanga whetū e hurihia ana te ahua whakamutunga e puta mai ana i te karu tirohanga. Ka whakamahia ngā karu tirohanga whetū hei tirotiro i ngā mea o te rangi pērā i ngā whetū me ngā aorangi he porowhita te āhua kia kore ai e raru ngā ahua hurihuri. I tetahi atu taha, ehara ngā mea kei runga i te mata o te Ao i te porowhita, nō reira, ki te puta he ahua hurihuri i te karu tirohanga whenua, ka uaua te tirotiro. He uaua ake te hanga karu tirohanga whenua he ahua poutū te ahua whakamutunga i te hanga karu tirohanga whetū he ahua hurihuri te ahua whakamutunga.
Ko te rahi o te koki e whakatau ana i te rahi o te ahua o te mea i hangaia ki te retina. mata. E ai ki te ahua kei te taha, ka iti ake te koki o te mea i te kanohi, ā, ka iti ake te ahua o te mea i hangaia ki te retina o te kanohi.
