infrared haskoki

Turanci masanin Herschel a 1800 aza hasken rana bakan. Tafki na Mercury a hannu daya ta hanyar toka mãsu yin baƙi. Abun Lura sun nuna wani karuwa a yawan zafin jiki. Saboda wannan, ya yanke shawarar cewa ma'aunin zafi da sanyio ne mai tsananin haskoki ganuwa ga mutum ido. Daga baya da suka kasance sunã kira infrared, watau zafi.

Wannan sakamako ya nuna lafiya karkace dafuwa. Mai tsanani, shi ya fara dumama farko, ba tare da canza launi, da kuma kawai to, a lõkacin Lagwani zama ja. Yana jũya, da Helix dabam daga infrared iyaka zuwa ganuwa ultraviolet radiation.

A yau mun san cewa duk jikin mika infrared haske. Light kafofin emitting infrared haskoki da ƙara zango, amma weaker Refractive kwana fiye da ja.

Heat ne radiation na infrared bakan, emanating daga motsi kwayoyin. A mafi girma da sauri, da girma da radiation, kuma wannan abu ya zama warmer.

Da zarar ya bude infrared haskoki, Wilhelm Ritter, wani Jamus likita, ya fara nazarin kishiyar sashi na bakan. Zango a nan ya kasa da na shunayya. Ya lura da mãsu yin baƙi azurfa chloride for Violet. Kuma shi ke faruwa da sauri fiye da amsa zango na bayyane haske. An gano cewa wannan radiation faruwa a lokacin electrons aka canza a kan m atomic bawo. Glass iya mamaye ultraviolet da haske, haka ma'adini ruwan tabarau da aka yi amfani da karatu.

A radiation tunawa da mutane da dabbobi da fata da kuma na sama shuka kyallen takarda. Kananan allurai ultraviolet radiation iya idon shafi Jihar kiwon lafiya, da karfafa tsarin na rigakafi da kuma yin bitamin D. Duk da haka, manyan allurai zai iya sa fata konewa da kuma lalata idanu, da kuma ma manyan ma da carcinogenic sakamako.

A amfani da ultraviolet

Ultraviolet radiation da ake amfani a magani (shi ne iya kashe cutarwa miroorganizmy), Sun, kazalika da hotunan. A sha na haskoki zama a bayyane. Saboda haka, wani na filin na aikace-aikace ne da amfani a samar da fitilu hasken rana.
