Kaiwhakarerekē whatu, e whakamahia ana hei whakahaere i te kaha o te mārama, te whakarōpūtanga o te hiko-whatu, te wera-whatu, te akutō-whatu, te whatu katoa, te ariā taketake o te pānga hiko-whatu.
Ko te whakarerekētanga whatu tētahi o ngā taputapu whatu whakauru tino nui i roto i te whakawhitiwhiti whatu tere-teitei me te tawhiti-poto. E ai ki te mātāpono whakarerekētanga, ka taea te wehewehe i te whakarerekētanga mārama ki te hiko-whatu, te wera-whatu, te acousto-whatu, te whatu katoa, me ētahi atu. Kei runga i te ariā taketake he maha ngā momo pānga hiko-whatu, te pānga acousto-whatu, te pānga magneto-whatu, te pānga Franz-Keldysh, te pānga Stark quantum well, me te pānga marara kawe.
Tekaiwhakarerekē hiko-whatuHe taputapu e whakahaere ana i te taupū whakaata, te mimiti, te kaha, te āhua rānei o te mārama putanga mā te huringa o te ngaohiko, te mara hiko rānei. He pai ake i ētahi atu momo whakarerekētanga i runga i te ngaronga, te kai hiko, te tere me te whakaurunga, ā, koinei hoki te whakarerekētanga e whakamahia whānuitia ana i tēnei wā. I roto i te tukanga tuku, tuku me te whiwhi whatu, ka whakamahia te whakarerekētanga whatu hei whakahaere i te kaha o te mārama, ā, he mea tino nui tōna mahi.
Ko te kaupapa o te whakarerekētanga mārama he whakaputa ke i te tohu e hiahiatia ana, i ngā mōhiohio rānei kua tukuna, tae atu ki te "whakakore i te tohu papamuri, te whakakore i te haruru, me te ārai i te pokanoa", kia māmā ai te tukatuka, te tuku me te kite.
Ka taea te wehewehe i ngā momo whakarerekētanga ki ngā wāhanga whānui e rua, i runga i te wāhi e utaina ai ngā mōhiohio ki runga i te ngaru mārama:
Ko tētahi ko te mana taraiwa o te pūtake mārama e whakarerekētia ana e te tohu hiko; ko tētahi ko te whakarerekē tika i te whakapaoho.
Ko te mea tuatahi e whakamahia ana mō te whakawhitiwhiti kōrero whatu, ā, ko te mea tuarua e whakamahia ana mō te rongo whatu. Hei whakarāpopototanga: te whakarerekētanga ā-roto me te whakarerekētanga ā-waho.
E ai ki te tikanga whakarerekētanga, ko te momo whakarerekētanga ko:
2) Te whakarerekētanga ā-wāhanga;
3) Te whakarerekētanga o te pōraihana;
4) Te whakarerekētanga auau me te roanga ngaru.
1.1, whakarerekētanga kaha
Ko te whakarerekētanga kaha o te māramatanga ko te kaha o te māramatanga hei mea whakarerekētanga, mā te whakamahi i ngā āhuatanga o waho hei ine i te huringa DC, puhoi rānei o te tohu māramatanga ki te huringa auau tere o te tohu māramatanga, kia taea ai te whakamahi i te whakakaha kōwhiringa auau AC hei whakanui, ā, ka ine tonu i te nui.
1.2, whakarerekētanga ā-wāhanga
Ko te mātāpono o te whakamahi i ngā āhuatanga o waho hei huri i te āhua o ngā ngaru mārama, me te ine i ngā rahinga ā-tinana mā te kite i ngā huringa āhua ka kiia ko te whakarerekētanga āhua whatu.
Ko te roa ā-tinana o te horapa o te mārama, te taupū whakaata o te reo horapa me tōna tohatoha ka whakatauhia te āhua o te ngaru mārama, arā, mā te whakarerekē i ngā tawhā o runga ake nei ka taea te whakaputa i te huringa o te āhua o te ngaru mārama hei whakatutuki i te whakarerekētanga āhua.
Nā te mea kāore e taea e te pūoko mārama te kite i te huringa o te wāhanga o te ngaru mārama, me whakamahi te hangarau pokanoa o te mārama ki te huri i te huringa wāhanga ki te huringa o te kaha o te mārama, kia taea ai te kite i ngā rahinga ā-tinana o waho, nō reira, me whakauru e rua ngā wāhanga o te whakarerekētanga wāhanga whatu: ko te tuatahi ko te tikanga ā-tinana o te whakaputa i te huringa wāhanga o te ngaru mārama; ko te tuarua ko te pokanoa o te mārama.
1.3. Te whakarerekētanga pōraritanga
Ko te huarahi māmā rawa atu ki te whakatutuki i te whakarerekētanga mārama ko te huri i ngā pōrari e rua tetahi ki tetahi. E ai ki te ariā a Malus, ko te kaha o te mārama putanga ko I=I0cos2α.
Ko: Ko I0 te kaha o te mārama e tukuna ana e ngā pōrari e rua ina rite tonu te papa matua; ko Alpha te koki i waenganui i ngā papa matua o ngā pōrari e rua.
1.4 Te whakarerekētanga auau me te roanga ngaru
Ko te mātāpono o te whakamahi i ngā āhuatanga o waho hei whakarerekē i te auau, i te roanga ngaru rānei o te mārama, me te ine i ngā rahinga ā-tinana o waho mā te kite i ngā huringa o te auau, i te roanga ngaru rānei o te mārama, ka kiia ko te whakarerekētanga auau me te roanga ngaru o te mārama.
