Isayensi Engemuva Kokuzinza Kwe-Granite Ezinhlelweni Zokubona.

 

I-Granite, idwala lemvelo eliyi-igneous elakhiwe ngokuyinhloko nge-quartz, i-feldspar, ne-mica, sekuyisikhathi eside laziwa ngobuhle nokuqina kwalo. Kodwa-ke, ukubaluleka kwalo kudlulela ngale kwezakhiwo kanye nama-countertop; i-granite idlala indima ebalulekile ekuzinzeni kwezinhlelo zokukhanya. Ukuqonda isayensi ngemuva kokuqina kwe-granite kungakhanyisa ukusetshenziswa kwayo ezindaweni ezinembe kakhulu njengaselabhorethri kanye nezindawo zokukhiqiza.

Esinye sezizathu eziyinhloko zokuthi kungani i-granite ithandwa ezinhlelweni zokukhanya ukuqina kwayo okuhle kakhulu. Ukwakheka okujiyile kwaleli dwala kuyenza ikwazi ukugcina ubuqotho besakhiwo ngaphansi kwezimo zemvelo ezahlukahlukene. Lokhu kuqina kunciphisa ukudlidliza nokuguquguquka, okuyizinto ezibalulekile ekusebenzeni kokukhanya. Kuhlelo lokukhanya, ngisho nokunyakaza okuncane kungabangela ukungalungi kahle, okungathinta ikhwalithi yesithombe. Ikhono le-granite lokumunca nokususa ukudlidliza lenza libe yinto efanelekile yokufaka izingxenye zokukhanya njenge-telescopes nama-microscopes.

Ngaphezu kwalokho, i-granite ine-coefficient ephansi yokwanda kokushisa. Le mfanelo ibalulekile ekusetshenzisweni kwe-optical, njengoba ukuguquguquka kwezinga lokushisa kungabangela ukuthi izinto zande noma zinciphe, okungaholela ekungalingani kahle. I-coefficient ephansi kakhulu yokwanda kokushisa kwe-granite iqinisekisa ukuthi izingxenye ze-optical zihlala zizinzile futhi zihambisana kahle ngisho nokushintshashintsha kwezinga lokushisa. Lokhu kuzinza kubaluleke kakhulu ezinhlelweni ze-optical ezinemba kakhulu, lapho ukunemba kubaluleke kakhulu.

Ngaphezu kwalokho, ukumelana kwemvelo kwe-granite ekugugeni kuyenza iqine ekusetshenzisweni kwe-optical. Ngokungafani nezinye izinto eziwohloka ngokuhamba kwesikhathi, i-granite igcina izakhiwo zayo, iqinisekisa ukusebenza okuzinzile nokuhlala isikhathi eside. Lokhu kuqina kunciphisa isidingo sokufakwa kabusha njalo, okwenza i-granite ibe ukukhetha okungabizi kakhulu kwesisekelo sezinhlelo ze-optical.

Ngamafuphi, isayensi ngemuva kokuqina kwe-granite ezinhlelweni zokukhanya ilele ekuqineni kwayo, ukwanda okuphansi kokushisa, kanye nokuqina kwayo. Lezi zakhiwo zenza i-granite ibe yinto ebalulekile emkhakheni wokukhanya, okuqinisekisa ukuthi izinhlelo zisebenza ngendlela enembile nethembekile. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, i-granite ngokungangabazeki izoqhubeka nokuba yitshe lesisekelo ekuthuthukisweni kwezinhlelo zokukhanya ezisebenza kahle kakhulu.
