Abantu abaningi abakwazi ukuhlukanisa phakathi kwerula yokusanhlamvu kanye nerula kazibuthe emshinini wokulinganisa wombono. Namuhla sizokhuluma ngomehluko phakathi kwabo.
Isikali se-grating inzwa eyenziwe ngomgomo wokuphazamiseka kokukhanya kanye ne-diffraction. Lapho ama-gratings amabili anephimbo elifanayo enqwabelene, futhi imigqa yenza i-engeli encane ngesikhathi esifanayo, khona-ke ngaphansi kokukhanya kokukhanya okuhambisanayo, ukukhanya okusabalaliswe ngokulinganayo kanye nemigqa emnyama kungabonakala ohlangothini oluqondile lwemigqa. Ibizwa ngokuthi ama-Moiré fringes, ngakho-ke ama-Moiré fringes awumphumela ohlangene wokuphazamiseka kanye nokuphazamiseka kokukhanya. Lapho i-grating inyakaziswa iphimbo elincane, ama-moiré fringe nawo anyakaziswa yi-fringe pitch eyodwa. Ngale ndlela, singakwazi ukukala ububanzi be-moiré fringes lula kakhulu kunobubanzi bemigqa yokugaya. Ukwengeza, njengoba i-moire fringe ngayinye yakhiwe ngeziphambano zemigqa eminingi yokugaya, lapho omunye wemigqa unephutha (isikhala esingalingani noma ukutsheka), lo mugqa oyiphutha kanye nomunye umugqa wokugaya Indawo yokuphambana kwemigqa izoshintsha. . Kodwa-ke, i-moiré fringe yakhiwe ngeziphambanomgwaqo eziningi zolayini wokugaya. Ngakho-ke, ukuguqulwa kwendawo yokuphambana komugqa kunomphumela omncane kakhulu kumphetho we-moiré, ngakho-ke i-moire fringe ingasetshenziselwa ukukhulisa kanye nomphumela omaphakathi.
Isikali kazibuthe inzwa eyenziwe kusetshenziswa isimiso sezigxobo kazibuthe. Isisekelo sayo siwumugqa wensimbi ozibuthe olinganayo. Izigxobo zayo zika-S no-N zihlukaniswe ngokulinganayo emgqeni wensimbi, futhi inhloko yokufunda ifunda izinguquko zezigxobo zika-S no-N ukuze zibalwe.
Izinga le-grating lithinteka kakhulu izinga lokushisa, futhi indawo yokusetshenziswa evamile ingaphansi kwama-degrees Celsius angu-40.
Izilinganiso ezivulekile zamagnetic zithinteka kalula ngamasimu kazibuthe, kodwa izikali kazibuthe ezivaliwe azinayo le nkinga, kodwa izindleko ziphezulu.
