Blackbody pāhawewe a me kona

Ua kapaʻia heʻeleʻele kino me ia, no ka mea, absorbs a pau e haule pu iho ma luna ona, (oia hoi, ia) pāhawewe i loko o ka hiki pae, a ma o aku. Akā, inā ua ole enaena i ke kino, i ka ikehu ua hou-kinoea hoʻi. Kēia pāhawewe ua kinoea ma kaʻeleʻele kino, ka mea, o ka pakahi hoihoi. Nā ho'āʻo mua i ka noiʻi i kona waiwai i, ua lawe maiʻo ia ma mua o ka muli o ke kükohu wale.

I ke kakahiaka nui 19th kenekulia, Dzhon Lesli ho okolohua me nā waiwai. E like me ka mea i huli mai,ʻaʻole waleʻeleʻele pouli absorbs a pau i ka hana 'ia ma kona hiki malamalama. Ua e hawewe i loko o ka welaʻula huahelu mea nui ka ikaika ma mua o ka mea 'ē aʻe, me ka māmā waiwai. Ka mea, ua i ka wela pāhawewe i mea okoa, mai a pau'ē aʻe ano o mau waiwai. Ka pāhawewe blackbody equilibrium, homogeneous,ʻaʻole hoʻi he ikehu hoolilo a me ka hilinaʻi nui ma luna o ke kino mahana. Ma ka wela i lawa ke kiekie o ka mea ka thermal pāhawewe ua i hiki, a laila, i kekahi kino me ka blackbody loaʻa iā ia kekahi waihoʻoluʻu.

Kēia hanana mea i kī ana wale i kekahi ʻano o ka ikehu, hiki ole ole ia,ʻo lohe. Oiai mākou e kamaʻilio e pili ana i thermal pāhawewe, na nā papakuhikuhi mua a me ka theories e pili ana i ka pae e nana me, ka mea, ua manaoia ma ka? Aieao o thermodynamics. Panina thermodynamics ke hooholo i ka ke kōā e ia i kā mākou no ka pāhawewe i ka haawiia mai wela, i ka i kuhikuhi ana, a pehea ka nui o ia e neʻe i ka hahana maoli nō kēia a me ka huʻihuʻiʻana. Naʻe, ka mea nele i ke kilokilo ana i ka ikehu puʻunaue i loko o ka pae o ka blackbody i nā mea a pau hawewe, a ma ka hana, ma ka ultraviolet laulā.

E like me ka manaÿo o ka panina thermodynamics, ka ikehu hiki ke kinoea ma kekahi'āpana, a me ka mea uuku e like me ka makemake. Akā, me heʻeleʻele kino e hoʻokuʻu akula ma pōkole hawewe, pono ia i ka ikaika o kekahi o kona (particles) nui loa, a me ka mea, ina ua hele i ka infinity i loko o ke kula o kaʻoi loa-nalu pokopoko. I ka ike maopopo i kēia mea,ʻaʻole e hiki, ua infinity ma na nā helu kaulike, a ua kapaia ka ultraviolet catastrophe. Wale Planck ka pähola i ikehu hiki ke kinoea i loko o discrete'āpana - quanta - kōkua e hoʻonā i ka pilikia. I kēia lā thermodynamics nā helu kaulike i kūikawā hihia o na nā helu kaulike o quantum ke kālaikūlohea.

Mua heʻeleʻele kino poe like me ka lua me ka ololi puka. Ka pāhawewe mawaho loaʻa i loko o ia i ka lua a me ke kemu ma ka paia. Ma ka pae o ka pāhawewe, a e i kaʻeleʻele kino, ma keia hihia, i like loa me ka ea puka pae o ke ana e komo ai, o ka luawai puka, he puka makani i loko o ka pouli lumi ma luna o ka pń mai ka lā, etc. Akā, ka hapanui o nā mea a pau me ia, i ka ia spectra o cosmic hawewe kāʻei kua pāhawewe o ka ke ao holoʻokoʻa a me na hoku, a me ka lā.

He maluhia, e olelo aku i ka nui o kekahi mau mea o (particles) ua okoa ikaika a, o ka oi ia e hoohalike ai blackbody pāhawewe. ikehu puʻunaue hālawa i loko o ka pae o ka blackbody Hōʻike 'ke ana helu regularities i loko o ka'ōnaehana o (particles), a me ka mea wale nō likeʻole i ka ikehu pū i hiki i ka AaOIeIOUIeXAOAaIN o discrete.
