→ leo80042:會不會是你把"狹縫寬度"和"狹縫間距"搞混了? 10/08 00:48
→ leo80042:高中學的雙狹縫干涉是假設狹縫寬度很小，沒有單狹縫繞射 10/08 00:49
→ leo80042:效應。但若把狹縫寬度也考慮進來，看到的條紋是干涉和繞 10/08 00:49
→ leo80042:涉結合在一起。(好久沒念了，有錯請指正謝謝^^") 10/08 00:50
→ grind:你實在很行....消逝場馬上又變成你以前學的... 10/08 00:56
→ grind:first of all, the scale of evanescent wave and that of 10/08 00:57
→ grind:diffraction are much different, about several orders.... 10/08 00:58
→ grind:the auther just talked about the "viewing screen". 10/08 00:58
→ grind:the slit width, a, is about one-tenth and the viewing 10/08 00:59
→ grind:screen will be smaller than the central bright zone. 10/08 01:00
→ grind:so that we don't take diffraction in consideration, when 10/08 01:01
→ grind:we are having a experiment of double-slit interferrence 10/08 01:02
→ grind:with a quite small slit width. 10/08 01:03
→ kevin60405:不太懂 所以就算波長>>狹縫寬 還是有干涉條紋? 10/08 17:14
