Te Hononga i waenganui i te Pūngao me te Auautanga Mārama
Kei roto i te whānuitanga o ngā momo irahiko hikohiko te whānuitanga o ngā momo irahiko hikohiko, mai i ngā ngaru reo irirangi roa-ngaru ki ngā hihi gamma poto-ngaru. Ko tētahi wāhanga nui o te mārama ki tēnei irahiko ko te hopu i te whanaungatanga i waenga i te pūngao me te auau mārama. Ehara i te mea ko tēnei hononga anake te tūāpapa o te ao ahupūngao engari he pānga mahi anō hoki ki ngā hangarau me ngā āhuatanga pūtaiao.
Te Irahiko Aukume me ōna Āhuatanga
Ko te irahiko aukume (EMR) he momo pūngao e tukuna ana, e mimitihia ana hoki e ngā matūriki kua utua, e whakaatu ana i te whanonga rite ki te ngaru i a ia e haere ana i te wāhi. Ka taea te whakaahua i ngā EMR katoa mā ō rātou roangaru (λ) me te auau (ν). Ko te roangaru te tawhiti i waenga i ngā tihi o te ngaru, ko te auautanga ia e tohu ana i te maha o ngā ngaru e whiti ana i tētahi pūwāhi kua hoatuhia mō ia hekona, e inehia ana i roto i te Hertz (Hz).
Ko te tere o te mārama (c), tata ki te 3 mita ia hekona i roto i te korehau, e herea ana ēnei āhuatanga e rua i roto i te whanaungatanga e homai ana e te whārite:
\[ c = \lambda \nu \]
Ina tae ki te mārama ki te pūngao e pā ana ki te irahiko hikohiko, ka mahi tēnei whārite hei piriti e hono ana i te auautanga ki tētahi atu ariā nui: te photon.
Te Āhua Kuantum o te Mārama: Ngā Photon
Nā te mahi a Albert Einstein i te tīmatanga o te rautau 20, inā koa tana whakamārama mō te pānga hikohiko, i whakatakoto te huarahi mō te tirohanga kuantum o te mārama. I roto i tēnei tirohanga, ka taea te whakaaro ko te mārama he mea hanga mai i ngā matūriki e kiia nei ko ngā photon, kei ia matūriki he pūngao kuantum. Ko te pūngao (E) o te photon he rite tonu ki te auau (ν) o te ngaru hikohiko e hono ana ki a ia, he whanaungatanga i homai e te whārite a Planck:
\[ E = h \nu \]
I konei, ko te "h" e tohu ana i te pūmau a Planck (\( 6.626 \times 10^{-34} \) joule-hēkona). E whakaatu ana tēnei whārite i tētahi mātāpono taketake: i te pikinga o te auau o te mārama, ka pikinga anō hoki tōna pūngao.
Te Whānuitanga me ōna Pānga
Hei mārama ki te hiranga o tēnei whanaungatanga, he mea nui kia whakaarohia te whānuitanga katoa o te hihi hikohiko. I te pito raro o te hihi, ka kitea e tātou ngā ngaru reo irirangi me ngā auau iti, nō reira, he iti te kaha o ngā photon. I te pikinga ake, ka tūtaki tātou ki ngā ngaruiti, ki ngā hihi whero whero, ki te mārama e kitea ana, ki ngā hihi ultraviolet, ki ngā hihi-X, me ngā hihi gamma. Ko ngā hihi gamma te pito auau teitei o te hihi, e mau ana i ngā photon tino kaha.
Māramatanga Kitea: He Tauira Mōhio
Ko te mārama kitea, te awhi whāiti o te whānuitanga hikohiko ka taea e te kanohi tangata te kite, he tauira whai hua mō te whanaungatanga i waenga i te pūngao me te auau. He roa ake te roangaru o te mārama whero, he iti ake hoki te auau i te mārama kikorangi. E ai ki te whārite a Planck, nō reira, he iti ake te pūngao o ngā photon o te mārama whero, engari he nui ake te pūngao o ngā photon o te mārama kikorangi, me tōna auau teitei ake.
Ehara i te mea ko tēnei rerekētanga o te pūngao anake te take e taea ai e te mārama UV—he nui ake te auau i te mārama e kitea ana—te whakapouri i te rā, engari e whakamārama ana hoki i te kaha kino o ngā hihi-X me ngā hihi gamma. Ko ō rātou auau tino teitei ka huri hei taumata pūngao teitei ka taea te whakakoi i ngā ngota me ngā ngota, ka arahi ki te kino koiora pea.
Nga tono Hangarau
He maha ngā hangarau e ārahi ana i te whanaungatanga i waenga i te auau mārama me te pūngao. Ka whakamahia e ngā oumu ngaruiti te auau me te pūngao motuhake o ngā ngaruiti hei whakaoho i ngā ngota wai i roto i te kai, hei whakamahana pai. I roto i ngā whakawhitiwhiti kōrero, ka whakamahia ngā auau rerekē hei tuku i ngā momo raraunga, ā, mā ngā auau teitei ake ka taea te tere ake i ngā raraunga.
I roto i te whakaahua hauora, ka whakaratohia e ngā hihi-X he tirohanga taipitopito o ngā hanganga o roto o te tinana, ko ngā MRI (e whakawhirinaki ana ki ngā ngaru reo irirangi) ka tukuna he mōhiohio tātaritanga rerekē. Ka whakamahia ngā hihi gamma i roto i ngā maimoatanga hauora, hei arotahi ki ngā pūtau matepukupuku, me te whakahoromata i ngā taputapu hauora, nā te mea he nui te kaha.
Tirohanga Astrophysical
He pai hoki te mārama ki te whanaungatanga pūngao-auau ki te ao tūroa, mā te mātakitaki i ngā auau rerekē o te māramatanga e tukuna ana e ngā tinana o te rangi ka āwhina i ngā kaimātai whetū ki te whakatau i ō rātou āhuatanga. Hei tauira, mā te ako i ngā hihi-X mai i ngā pōro pango, i ngā hihi gamma rānei mai i ngā supernovae ka whakamārama i ngā taiao me ngā āhuatanga tino nui o te ao tūroa.
Ko te tirotiro irahiko, te ako i te taunekeneke i waenga i te matū me te irahiko hikohiko, e whakamahi ana i te whanaungatanga pūngao-auau hei tautuhi i te hanganga o ngā whetū me ngā tupuni tawhiti. Ka mimiti, ka tuku mārama ia huānga i ngā auau motuhake, e āhei ai ngā kaipūtaiao ki te whakatau i tō rātou aroaro me te nui o ngā mea o te rangi.
Te Hangarau Irahiko me tua atu
I te tauine hohonu ake, he mea nui tēnei whanaungatanga i waenga i te pūngao me te auau o te mārama i roto i te miihini matū. Ka mimiti, ka tukuna rānei e ngā irahiko i roto i ngā ngota ngā photon hei peke i waenga i ngā taumata pūngao, me te pūngao o te mārama kua mimitihia, kua tukuna rānei, ka inehia kia rite ki te whanaungatanga a Planck.
Ka tautokohia hoki e tēnei hononga ngā whanaketanga o te hangarau taiaho. Ka whakaputahia e ngā taiaho te māramatanga mārama o tētahi auau motuhake, ā, nō reira te pūngao, he mea whai hua i ngā mea katoa mai i te tapahi rauemi ki te mahi pokanga ngawari me te whakahohe i te whakawhitiwhiti tere.
Opaniraa
Ko te whanaungatanga i waenga i te pūngao me te auau o te māramatanga he poutokomanawa o te ahupūngao tawhito me te ahupūngao hou. Ka pāorooro puta noa i ngā āhuatanga katoa o te tūhuratanga pūtaiao me te tono hangarau, mai i ngā mahi o ia rā o ngā taputapu o te whare ki ngā mea ngaro hohonu o te ao tūroa. Ehara i te mea ka whakarei ake i tō tātou māramatanga ki te ao tūroa anake tēnei mātāpono taketake, engari ka whakamanahia hoki ngā auahatanga e whakarei ake ana i te kounga o tō tātou oranga. I te whanaketanga haere o te pūtaiao, ko te kanikani uaua i waenga i te pūngao me te auautanga ka haere tonu ki te hura i ngā mea whakamiharo me ngā whai wāhitanga hou.
