ʻO ka Diffraction o ke Mālamalama: He Hanana e Hoʻonāukiuki ai i nā Palena ʻIke
He hanana kino ka diffraction o ka mālamalama a mākou e ʻike ʻole ai i nā manawa a pau, akā he kuleana koʻikoʻi kona i nā ʻano he nui o ke ola o kēlā me kēia lā a me ka ʻenehana. ʻO ke kumu, pili ka diffraction i ke kūlou ʻana o nā nalu mālamalama i ko lākou hele ʻana ma kahi puka a i ʻole e hālāwai me kahi mea keakea i ko lākou ala. Hōʻike kēia hanana i nā mea he nui e pili ana i ke ʻano kumu o ka mālamalama ma ke ʻano he nalu a hāʻawi i nā ʻike hohonu i ke ʻano o ka hana ʻana o ke ao holoʻokoʻa ma ka pae microscopic.
He Moʻolelo Pōkole
Ua wehewehe mua ʻia ke kumumanaʻo o ka diffraction e ka ʻepekema Italia ʻo Francesco Grimaldi i ke kenekulia 17, nāna i ʻike ʻaʻole hele mau ka mālamalama ma nā laina pololei loa. Ua noiʻi hou ʻia kēia ʻike ma hope e Christiaan Huygens lāua ʻo Thomas Young, nāna i hāʻawi i nā kumumanaʻo koʻikoʻi e pili ana i ke ʻano o ka nalu a me ke komo ʻana o ka mālamalama. ʻO ka hoʻokolohua pālua ʻelua a Young, ma ke ʻano kūikawā, ua hāʻawi i nā hōʻike ikaika e hōʻike ana ka mālamalama i nā ʻano nalu, kahi manaʻo i hōʻole i ka manaʻo ma mua e hana wale ana ka mālamalama ma ke ʻano he mau ʻāpana.
Nā Kumumanaʻo Kumu o ka Diffraction
I ka ʻōlelo maʻalahi, hana ʻia ka diffraction ke hele nā ale māmā ma kahi puka e like me ka nui o ko lākou nalu, a i ʻole ke launa pū ka mālamalama me ka lihi o kahi mea. ʻO ka hopena he ʻano hoʻopilikia paʻakikī, kahi e kūlou ai nā nalu māmā a pālahalaha. ʻŌlelo ke kumumanaʻo o Huygens hiki ke manaʻo ʻia kēlā me kēia kiko ma kahi nalu he kumu o nā nalu lua. A laila launa pū kēia mau nalu lua me kekahi e hana i nā ʻano a mākou e ʻike ai ma ke ʻano he diffraction.
Hiki ke ʻike ʻia nā ʻano diffraction ma ke ʻano he moʻo o nā kiko ʻālohilohi a me nā kiko ʻeleʻele. Hoʻokumu ʻia kēia e ka hoʻopilikia kūkulu a me ka luku ma waena o nā nalu mālamalama diffracted. Hana ʻia ka hoʻopilikia kūkulu ke hālāwai kahi piko nalu me kekahi piko nalu ʻē aʻe, e hopena ana i ka hoʻonui ʻia o ka ikaika o ka mālamalama. I ka ʻaoʻao ʻē aʻe, hana ʻia ka hoʻopilikia luku ke hālāwai kahi piko nalu me kekahi awāwa nalu ʻē aʻe, e hoʻopau ana iā lākou kekahi i kekahi.
Nā Hoʻohana o ka Diffraction i ke Ola o kēlā me kēia Lā
ʻAʻole wale ka diffraction māmā he hanana i ʻike ʻia i loko o nā keʻena hoʻokolohua physics. Hoʻonui ʻia kāna mau noi ma nā ʻano kahua like ʻole. ʻO kahi laʻana ka hoʻohana ʻana i kahi grating diffraction, kahi e hilinaʻi nei i nā ʻano diffraction e wāwahi i ka mālamalama i loko o kāna mau spectra ʻāpana. Hoʻohana nui ʻia kēia i ka spectroscopy, kahi e hiki ai i nā ʻepekema ke kālailai i ka haku mele kemika o nā mea e pili ana i ka mālamalama a lākou e hoʻopuka ai.
I loko o ka ʻenehana optical, hoʻohana ʻia ka diffraction e hoʻoponopono i nā aberrations i nā ʻōnaehana optical. Hāʻawi ka Diffraction i ka ʻike koʻikoʻi e kōkua i ka hoʻolālā ʻana o nā aniani a me nā mea hana optical ʻē aʻe e hana i nā kiʻi ʻoi aku ka ʻoi a me ka pololei. Hilinaʻi nā ʻenehana kiʻi e like me nā microscope electron a me nā telescope holomua i ka ʻike o ka diffraction e hoʻomaikaʻi i ka hoʻonā a me ka maikaʻi o ke kiʻi.
Hoʻohana ʻia ke ʻano o ka diffraction e hana i nā ʻano holographic. Hoʻohana nā Holograms, i hoʻohana ʻia i nā kāleka ID palekana a me nā hoʻonohonoho kiʻi, i nā ʻano diffraction e mālama a hana hou i ka ʻike ʻike ʻekolu-dimensional.
Diffraction a me ka Hoʻomohala ʻenehana
He kuleana koʻikoʻi ko ka diffraction i ka hoʻomohala ʻana o ka ʻenehana hou, ʻoi aku hoʻi ma nā kahua o ke kamaʻilio ʻana a me ke kiʻi ʻana. No ka laʻana, ma nā pūnaewele kamaʻilio fiber-optic, hoʻohana ʻia ka diffraction māmā e hoʻomaikaʻi i ka hoʻoili ʻikepili. Ma ka hoʻonohonoho ʻana i nā olonā lahilahi i loko o nā hui kikoʻī, hiki iā mākou ke hōʻemi i ka nalowale o ka hōʻailona ma muli o ka diffraction nui.
Eia kekahi, hoʻohana nā kāmela ma nā polokalamu kelepona i nā hopena o ka diffraction e hoʻomaikaʻi i ka nānā ʻana. Ma ka hoʻohana ʻana i kahi puka liʻiliʻi, kahi e hoʻopuka ai i ka diffraction nui aʻe, hiki i ke kāmela ke hoʻokō i ka hohonu o ke kahua, ʻoiai ma kahi hoʻonā haʻahaʻa.
Ua noʻonoʻo ʻia hoʻi nā hopena diffraction i ka hoʻolālā ʻenehana laser. Hoʻohana ʻia nā lasers ma nā ʻano hana like ʻole, mai ke ʻoki kino lapaʻau a hiki i ka hana ʻoihana. ʻO nā haʻawina i aʻo ʻia mai nā haʻawina diffraction e kōkua i ke alakaʻi a me ka hoʻopuehu ʻana i nā kukuna laser me ka palekana a me ka pololei.
ʻO ka Diffraction Kūlohelohe: Ka Haʻaheo o ka Lā a me ke Ānuenue
ʻAʻole wale ka Diffraction he hanana kino me nā noi loea; he ʻike maka hoihoi pinepine ia i ke kūlohelohe. ʻO ke kiʻi o ke ānuenue kahi laʻana maikaʻi o ka diffraction māmā, kahi e hana ai nā kulu wai i ka lewa ma ke ʻano he prism e hoʻolaha ana i ka lā i loko o kona spectrum. Ma kēia hanana, ʻike mākou i ka hopena o ka hana hui o ka refraction, reflection, a me ka diffraction.
Pēlā nō, ʻo nā halo e ʻike ʻia i kekahi manawa a puni ka lā a i ʻole ka mahina, ʻo ia ka hopena o ka diffraction o ka mālamalama e nā kristal hau i ka lewa. Hoʻokumu kēia i kahi apo kukui i hoʻopilikia ʻia e ʻike ʻia e ʻālohilohi me nā waihoʻoluʻu kala a puni ka mea lani.
ʻO ka wā e hiki mai ana o ka noiʻi a me nā noi Diffraction
Me ka holomua o ka ʻenehana a me ke ʻano hana ʻepekema, ke hoʻomau nei ko mākou ʻike i ka diffraction e hoʻonui. Ke wehe nei kēia i ke ala no nā pilikia hou a me nā manawa kūpono i ka ʻepekema a me ka ʻenekinia. ʻO ka noiʻi diffraction ma ka pae quantum, no ka laʻana, e ʻimi ana i ke ʻano o ka launa pū ʻana o ka mālamalama me nā mea ma ka pae subatomic, kahi e paʻa ai ka hiki ke hana hou i ka helu quantum a me nā kamaʻilio.
Eia kekahi, ʻo ka hoʻomohala ʻana i nā mea hou e hiki ke hoʻohana a hoʻololi i ka diffraction me ka ʻoi aku ka maikaʻi e alakaʻi i nā hoʻomaikaʻi ʻana i nā ʻano ʻenehana like ʻole, mai ke kiʻi ʻana i nā kiʻi lapaʻau a hiki i ka hoʻomohala ʻana i nā kumu ikehu ʻoi aku ka maikaʻi.
ʻO ka mea hope loa, ʻo ke aʻo ʻana i ka diffraction māmā e kōkua iā mākou e hoʻomaopopo maikaʻi i ke ʻano o nā nalu māmā a me kā lākou pilina me ke kaiapuni. Mai nā noi hana i ka ʻenehana a hiki i ka nani i ʻike ʻia i ke kūlohelohe, ʻo ka diffraction māmā kahi hanana e hoʻopili ai i ke kumumanaʻo ʻepekema me ka ʻike kanaka o kēlā me kēia lā a hoʻoulu i nā holomua i ka wā e hiki mai ana.
