Akukho okuhle ngaphezu kokuqala kosuku ngesibhakabhaka esicace bha, ngombala omuhle oluhlaza okwesibhakabhaka, akunjalo? Impela wake wazibuza ukuthi kungani unalowo mbala wesici hhayi omunye. Kungashiwo, ngaphandle kwephutha, ukuthi yi umbuzo wezigidi zamadola udinga impendulo maduze.
Kanjalo. Kule ndatshana ngizochaza Kungani isibhakabhaka siluhlaza ukuze kusukela manje kuqhubeke, ngaso sonke isikhathi uma ubheka phezulu esibhakabhakeni, uyazi ukuthi kungani sikubona kulowo mfanekiso.
Umbala oluhlaza okwesibhakabhaka
Incazelo elula yokuthi kungani isibhakabhaka siluhlaza kanje: lo mbala ungenxa yokuhlangana kokukhanya okumhlophe okuqhamuka eLangeni nama-molecule atholakala emoyeni. Kodwa-ke, umbala ovela ekusebenzisaneni phakathi kokukhanya okumhlophe okuvela eLangeni nakuma-molecule akudingeki kube luhlaza okwesibhakabhaka. Eqinisweni, njengoba amahora ehamba, isibhakabhaka siveza imibala ehlukahlukene nemibala esibhakabhakeni. Lokhu kungenxa yokunyakaza okujikelezayo nokuhumusha koMhlaba kanye nezinguquko ezahlukahlukene ezenzeka kuwo wonke umoya osemkhathini. Kepha kusekhona okuningi ...
Lapho ukukhanya okumhlophe okuvela elangeni 'kudlula' emkhathini, kusakazeka kuyo yonke imibala yayo: igagasi elifushane (eliluhlaza okwesibhakabhaka nokunsomi) negagasi elide (elibomvu nephuzi). Njengoba imisebe eluhlaza okwesibhakabhaka ne-violet inokuphambuka okuphezulu, zihlakazeka kakhulu ngaphambi kokufinyelela emhlabathini esiwunyathela. Lapho zifinyelela emehlweni ethu, sinomuzwa wokuthi zihlala esibhakabhakeni sonke lapho zivela ngqo enkanyezini yethu: ilanga.
Le yincazelo ye- kungani endaweni ejulile isibhakabhaka simnyama bhuqe. Njengoba zingekho izinhlayiya zomoya ezingakhanya ekukhanyeni kwelanga, awukwazi ukwehlukanisa imibala ehlukahlukene isibhakabhaka esivela emkhathini okungenzeka ukuthi inayo.
I-spectrum ebonakalayo yokukhanya
Ukuqonda kangcono le ncazelo, ngicabanga ukuthi kulula ukuyichaza yini ukukhanya okubonakalayo kokukhanya nokuthi kubaluleke kangakanani ngesihloko esibhekene naso.
Amehlo abantu ayisimangaliso sangempela (yebo, noma ngabe kufanele ugqoke amalensi wokuxhumana), kusukela ingahlukanisa imibala enhlobonhlobo esukela ku-ultraviolet -ikunobude obungu-400nm-, ukuya ku-infrared -750nm-. La magagasi aziwa ngokuthi ukukhanya okubonakalayo, okungukuthi, sibona into, noma kulokhu isibhakabhaka, esikhanyiselwa okuthile (ilanga).
Ngokuya ngobude besilinganiso, sizoyibona ngombala owodwa noma omunye. Lapho siyibona iluhlaza okwesibhakabhaka, kungenxa yokuthi sibona amagagasi avela phakathi 435 no-500nm. Kepha uma ufuna ukwazi ukuthi umbala ngamunye unabuphi ubude bamandla, mhlawumbe lokhu kuzokusiza:
- 625 - 740: Bomvu
- 590 - 625: Orenji
- 565 - 590: Okuphuzi
- 520 - 565: Okuluhlaza okotshani
- 500 - 520: Cyan
- 435 - 500: Luhlaza okwesibhakabhaka
- 380 - 435: Violet
Akuzona zonke izilwane ezibona umhlaba unombala ofanayo nathi. Kangangokuthi izinja, ngokwesibonelo, azihlukanisi okubomvu noma okuluhlaza okotshani. Uhlobo ngalunye lunemibala yalo ehlukahlukene, kuya ngokuthi umbono ubaluleke kangakanani kuye.
Eminye imibala yesibhakabhaka
Yize singase sicabange ukuthi isibhakabhaka singabonakala kuphela ngemibala ehlukahlukene eluhlaza okwesibhakabhaka, empeleni kwesinye isikhathi sizosibona ngeminye imibala. Futhi kungenxa yezimo ezithile izehlakalo ezinjenge uthingo, the imiqhele yelanga futhi i ama-halos wokukhanya.
Njengokuthi kwakuyi-prism, ukukhanya okumhlophe okufinyelela emkhathini kubanga ubude bamaza ahlukene, okwenza kwesinye isikhathi isibhakabhaka sikhiqize izenzakalo ezimangalisayo njengalezo ezibalulwe esigabeni esandulele. Yize kunjalo, kuleli cala awekho ama-prism, kepha izinhlayiya zamanzi.
Futhi ngasendleleni, uyazi ukuthi kungani kwesinye isikhathi isibhakabhaka sibukeka sibomvu noma siwolintshi? Cha? Akukho okwenzekayo. Nayi incazelo: lokhu kwenzeka ikakhulukazi lapho kushona ilanga. Kungenxa yokuthi imisebe yelanga ngalezo zikhathi kufanele ihambe ibanga elide kakhulu kunasemahora emaphakathi osuku ukuze ifinyelele kithi. Okokuqala kubukeka njengewolintshi bese kubomvu, ngoba ama-wavelengths amafushane (njengoba, njengoba sibonile, anemibala eluhlaza okwesibhakabhaka nonsomi) aya ngokuya ehlakazeka futhi ubude obude kuphela obufinyelela kithi (obomvu).
Uma ntambama sinesibhakabhaka esiguqubele, imisebe yelanga izokhanyisa amafu asuka phansi, nawo azobonwa ngamehlo ethu. Khumbula ukuthi isibhakabhaka ngeke sibheke ngokuya sibomvu, kepha umbala oluhlaza okwesibhakabhaka uzobuna njengoba usakazeka yizinhlayiya zomoya. Kuyathakazelisa, awucabangi?
Manje uyazi ukuthi kungani isibhakabhaka siluhlaza okwesibhakabhaka ... noma, kuhle, neminye imibala nayo 🙂.
Jabulela isibhakabhaka!
Kepha kungani amafu abukeka emhlophe? Nenyanga nayo! Kungani?
Sawubona albi.
Amafu akhiwa ngamaconsi amanzi. Umbala uyehluka kuya ngosayizi walawa maconsi nelanga; Isibonelo, uma emakhulu, amehlo ethu azowabona empunga noma amnyama ngoba amafu avimba ukudlula kwemisebe yelanga eya emhlabeni.
Ngokuqondene neNyanga, kahle, empeleni isathelayithi yethu yakhiwe ngezinto ezimnyama; kodwa-ke, isikhala simnyama kakhulu. Ngakho-ke, njengoba sizungezwe ubumnyama obuphelele kubonakala ngathi kumhlophe, ikakhulukazi ebusuku nenyanga egcwele.
Iqiniso elithandekayo ukuthi amehlo omuntu ayazwela ekukhanyeni, akhiwe ngezinduku nezigaxa. Ngenxa yangaphambilini singakwazi ukuhlukanisa imibala, inqobo nje uma kunokukhanya okwanele; okuphambene kwenzeka ngamasekhondi, okungukuthi, bathola ukukhanya, kepha imibala ... hhayi kakhulu.
