He pāhawewe

Electromagnetic a he pāhawewe uhi i ka spectral māhele'āina ma waena o ka hawewe electromagnetic, i ike i ke kanaka maka a me kona ula kōkua a me ka hawewe a me ka hawewe pāhawewe. Ka nui likeʻole i loko o ka'ōnohi waiwai o ka 'ona ike ma waena o ka pokole i loko o ka malamalama welaʻula a me ka hiki. No ka laʻana, no ka pōkole-ho'āli aʻe he pāhawewe i loko o ka wai kekahi mau kenimika manoanoa opaque.

About 50% o ka pāhawewe lā e kau mai ma luna o kēiaʻano. He hapa o ka huna a me ka incandescent kukui e like me kekahi kukuna hiki o K'lauea he pāhawewe. I inoa mea, hoʻohana 'photovoltaic a me thermal pa alima a me kūikawā kiʻi.

Ma ka laulā o ka pāhawewe i ekolu eiiiiiaiou: pōkole-nalu, meakino-nalu a me ka lōʻihi-nalu māhele 'āina. Hou hawewe e māheleʻia i loko o sublimated a terahertz pāhawewe.

Kanaka ili makaukau pāhawewe mai ka wela mea, e like me ka mea thermal ka waiʻona ma, pela no ka mea, ua i kapaia "wela." Ke kōā hawewe hou wela, hilinaʻi nui ma luna o ka paio hahana maoli nō mahana. Inā ka wela mea kiʻekiʻe,ʻo ke kōā mea pōkole, a me ka nui ana o kona ea puka ma luna. Ka pīhoihoi Ion a me nā'ātoma hoʻokuʻu akula he pāhawewe. Ma keia laulā, ma kŘpa a haʻahaʻa ana wela a me ka mea electromagnetic a pāhawewe pae blackbody.

Astronomer William Herschel loaa electromagnetic a pāhawewe i ka 1800, ma hope i welaʻula malamalama i ua? Anoee ma au mamuli. Kona mall Herschel manao me ka hoʻohana 'ana wela. E like me ka hopena o ia mea, ka mea i hoike mai i kekahi mau apana o ka hiki pae mahana hana okoa. Herschel Ua hōʻike 'ia kēia:ʻo kā mākou wela, a moe mawaho o ka paʻa kūhohonu loaʻulaʻulaʻano, he mea hiki, a ka mea i nanaia refraction.

Hoikehonua, keʻena hoʻokolohua kumu o he pāhawewe i ka nānā 'ana ma luna o ka p ÷ haku-moku'āina hakakino kinoea kukuna. Ka mea, ua hoʻoneʻe a me ka paʻa ea puka alapine (frequency).

E aaeno thermal pāhawewe kūikawā kiʻi papa i hoʻohana. Photoresistor photoelectric mīkini hopu ka mea hewa, a i ka nui lehulehu huahelu o ka pā lonoaʻili.

Ka mea, i ka hana hiki i ka pāhawewe. Kona waiwai ka poe hana pela e ka mea hiki ke hoʻohana 'ia i loko o nā mahinaʻai:

• lapaau - ma physiotherapy;
• sterilization o ka ai nā huahana no disinfection;
• kākou e hooponopono - ma ka kīwī loihi kumu hoʻohālikelike a, 'akomi a me ka mālama' ia hoʻi kekahi, i kekahi mau Ke Ana Hoʻohālike o ka lawe lima kaul;
• pena - hoolilo ikehu a me ka lākiō o ka nui haʻahaʻa ma mua me ka au paialewa ke hana;
• me he Anati-ka popopo hope paha;
• ai hana - nä hawewe electromagnetic i kekahi mau huahelu i thermal a liluwelo hopena ma luna o ka huina hoonui, i kokua hōʻeleu i biochemical loli 'ana ma biopolymers;
• mahiʻai ka hana;
• makahiki paio hahana maoli nō alanui a me na hale i ka papa a me ka hou paio hahana maoli nō;
• o kéu hoʻomaopopo i ka authenticity o ke kala, etc.

He pāhawewe hiki i ka hewa ana i kanaka maka. Ma ia mau wahi a pau he mea kiʻekiʻe wela, he pāhawewe hiki e weliweli no ka maka, a ina ka mea, ua i pu ma ka hiki malamalama kahi. Ma kēia hihia ia mea pono e hoʻohana aiiay goggles.

Ma nā hihia, he pāhawewe kumuʻino i kānaka hiki ole. He loa palekana, a 'aʻole i kekahi mea i' ano like me ka ultraviolet a X-kukuna.

He pāhawewe, hoʻohana no ka imu, eʻai ka loaʻono, e like me ka mea i koe a pau o na nā minelala hao a me nā wikamina, a me ka hawewe, ka mea, aole i i kekahi mea e hana ai.

Ma kekahi mau mākou ke olelo aku i kaʻaneʻane kekahi o na wahi ma ka pāhawewe ua ole hoʻohana i kēia lā.
