Ka manaʻo
William Herschel (1738-1822) makemake e noiʻi i nā ʻokoʻa wela ma waena o nā kala like ʻole o ke kukui ʻike ʻia i ka hoʻomaka ʻana o ke kenekulia 19.
Ke hoʻokokoke ʻana
Herschel, he mea kilo hōkū a haku mele, Ua hana ʻo ia i kēia ma ka hoʻohuli ʻana i ka lā me ke aniani prisma. A laila ua kau ʻo ia i nā thermometer i nā kala like ʻole o ka māmā. ʻO ka hope, ua kau ʻo ia i kahi ana wela 'control' ma kahi ʻaʻohe kukui. E ana kēia i ka wela o ka ea a lilo i mea kuhikuhi no nā ʻokoʻa wela o nā mea wela ʻē aʻe.
Ka hopena
Ua hoʻolālā ʻo ia e unuhi i ka mahana kuhikuhi o ka thermometer i ka pōʻeleʻele mai nā mahana "kiʻekiʻe" o nā kala like ʻole o ka mālamalama.. Eia nō naʻe, ʻo kona pūʻiwa, ʻoi aku ka kiʻekiʻe o ka mahana o ka thermometer control ma mua o nā mea ʻē aʻe!
ʻAʻole hiki iā Herschel ke wehewehe i ka hopena ma kekahi ʻano a manaʻo ua hāʻule kāna hoʻokolohua.
Ua hoʻomau ʻo ia i ka ʻimi. Ua hoʻoneʻe ʻo ia i ka thermometer mana i nā kūlana ʻē aʻe (ma luna a ma lalo o ke kala kala) kahi i anaia ai ka ea wela.
Ua hoʻoholo ʻo ia he pono e loaʻa kekahi radiation ʻike ʻole ʻia ma waho o ka ʻāpana ʻulaʻula o ka spectrum kala.
Nā haʻawina
ʻO kekahi kumu i kūleʻa ai ʻo William Herschel ma ke ʻano he kilo kilo a me ka mea noiʻi, ma muli paha o kona noho ʻana, ʻoiai ʻaʻole i holo koke ka manaʻo i manaʻo ʻia.
Eia hou aku:
Ma waho aʻe o ka 'mea hana' o ka pāhawewe infrared, ua ʻike ʻia ʻo Herschel ʻo ka astronomer nāna 1781 Ua ʻike ʻia ʻo Uranus. Ua hana ʻo ia i nā mea ʻike astronomical hoihoi hou aʻe.
ʻOkoʻa loa nā noi o ke kukui infrared, mai ke kamaʻilio uea ʻole pōkole (mana mamao) i nā noi koa e ʻimi i ka ʻenemi.
