LCP-20 Cov Cuab Yeej Siv Los Tshawb Fawb Txog Kev Cuam Tshuam

Kev Piav Qhia Luv:

Tus nqi pheej yig.
Raws li qhov tsis zoo ntawm cov khoom siv sim diffraction teeb pom kev zoo ib txwm muaj, cov cuab yeej sim diffraction teeb pom kev zoo tshiab tau tsim. Raws li qhov xav tau ntawm kev sim, cov cuab yeej sib xws tau muab tso ua ke. Cov cuab yeej sim no tuaj yeem siv rau kev sim ua qauv pom kev zoo nrog rau kev sim kho qhov muag tshwj xeeb. Cov cuab yeej sim diffraction teeb pom kev zoo sib xyaw ua ke kev sim cuam tshuam thiab kev sim diffraction rau hauv ib lub cuab yeej sim, uas tuaj yeem ua ob qho kev sim cuam tshuam teeb pom kev zoo thiab kev sim diffraction teeb pom kev zoo.
