Luyini uthingo lwenkosazana
Kalula nje uthingo luyi-arc enemibala eminingi eyakha esibhakabhakeni. Mingaki Imibala Othingolweni?
Kunemibala engu-7 othingo. Indlela enhle yokubakhumbula ukusebenzisa imvumelwano:
Uhlamvu lokuqala lwegama ngalinye lumelela omunye wemibala yothingo.
- Okubomvu – red;
- Okuphuzi – yellow;
- Okuluhlaza / okotshani – green;
- Okuluhlaza / okwesibhakabhaka – blue;
- Okusawolintshi – orange;
- Enzulu – indigo
- Ekhwithi – violet
Yini eyenza uthingo?
Uthingo yinto yesimo sezulu eyakhiwa lapho ukukhanya, ngokuvamile okuvela eLangeni, kudlula kumaconsi amanzi alenga emkhathini. Umkhathi ungqimba lwegesi oluzungeza uMhlaba. Kusenza sikwazi ukuphefumula futhi kusivikele emisebeni eyingozi ekhishwa yiLanga.
Ukuze ukwazi ukubona uthingo, ngokuvamile udinga ukufulathela iLanga, ngoba uthingo ngokuvamile luzovela engxenyeni yesibhakabhaka ebhekene ngqo neLanga.
Isayensi yothingo
Uthingo luwumphumela wezimo ezintathu zesayensi: ukubonakaliswa, ukuhlehla kanye nokuhlakazeka kokukhanya.
Irefraction ukuguqulwa kwejubane lewavelength ngenkathi idlula ezintweni. Lokhu kuvame ukubonakala ngezinto ezikhanyayo nezibonisa ngale, njengengilazi noma amanzi. Ukwakha uthingo, ukukhanya okumhlophe okuvela eLangeni kungena ethonsini lamanzi futhi kunqanyulwe.
Idala ukuhlakazeka ngendlela efanayo lapho ukukhanya okumhlophe kukhiqiza khona ukukhanya okuningi lapho kudlula kuprism.
Ngemuva kweconsi lamanzi, le spectrum iboniswa futhi iphinde iphinde iphinde iphinde lapho ishiya ithonsi.
Wonke umbala emisebeni yokukhanya unobude beza obuhlukile. Ngenxa yalokhu, lapho iphikiswa, ngayinye izoshintsha isivinini kancane futhi igobe ngokwezinga elihlukile, ihlukanise imibala futhi iyenze ibonakale emehlweni ethu.
Uthi bewazi?
Uthingo lwenkosazana empeleni luyindilinga egcwele! Singabona kuphela ukukhanya okuphindiwe ngamaconsi emvula ngaphezu komkhathizwe, okusho ukuthi abantu abaphansi bangabona uhhafu wothingo.
Ukuze ukwazi ukubona okugcwele kufanele uphakame kakhulu esibhakabhakeni!
