LCP-19 Kev Ntsuas Qhov Hnyav ntawm Diffraction

Kev Piav Qhia Luv:

Lub tshuab sim no yog tsim rau kev qhia txog kev sim physics dav dav hauv cov tsev kawm qib siab thiab tsev kawm qib siab. Cov yam ntxwv tseem ceeb suav nrog kev ua haujlwm ruaj khov, kev ua haujlwm yooj yim thiab kev nyeem ntawv raug. Nws pab cov tub ntxhais kawm kom nkag siab txog cov ntsiab cai yooj yim ntawm Fraunhofer diffraction, thiab ntsuas qhov kev faib tawm ntawm Fraunhofer diffraction. Los ntawm lub tshuab no, cov tub ntxhais kawm tuaj yeem txhim kho lawv cov txuj ci sim thiab kev txawj ntse txheeb xyuas.
