[問題] 磁場B的能量

[ Physics ]4 留言, 推噓總分: +3

作者: waibun - 發表於 2007/09/23 16:23(18年前)

4^F→profyang:嚴謹的推導要用向量微積分...你可以參考電磁學的書09/25 13:39

請問圓孔繞射中央一定是一塊亮區嗎?

作者: pianoboy - 發表於 2007/09/19 02:27(18年前)

1^F推profyang:不可能,因為你在疊加電場時,最後光強會跑出sin^2(kx-wt)09/19 10:41

2^F→profyang:這項對時間平均值一定是1/2,而我們看到的一定都只是平均09/19 10:43

3^F→profyang:值,所以你一定不會在中央看到暗區.09/19 10:44

[問題] 光的intensity

1^F推profyang:intensity一般指的是光的能量密度09/18 15:02

[問題] 光碟表面的彩色光影

6^F推profyang:干涉繞射本來就沒明顯的分界,反正都是電場的疊加就對了09/17 20:56

8^F推profyang:可是像光柵理論上是N狹縫繞射阿,但我們還是說他是繞射光갠09/17 23:41

9^F→profyang:柵...基本上還是很少也不用嚴謹的訂出界線吧...09/17 23:42

12^F推profyang:那麼光柵究竟算繞射或干涉呢?畢竟他的計算模型是和N狹縫09/18 10:31

13^F→profyang:干涉一樣的阿?09/18 10:33

14^F→profyang:而N狹縫干涉的狹縫數是有限的,並不是無限的吧?09/18 10:33

16^F推profyang:無限多09/18 14:56

17^F推profyang:而且他是用積分，而光柵和多狹縫干涉則是級數,所以我一直09/18 14:58

18^F→profyang:覺得光柵和多狹縫干涉是一樣的,因為他們數學模型根本一樣09/18 15:00

21^F推profyang:那在實際上，不就都是繞射了?因為實際上都是電子在出放出09/18 15:20

22^F→profyang:電磁波...而電子應該可視做無限多個吧?09/18 15:22

25^F推profyang:等等，所以你的意思是多狹縫干涉也算是繞射嗎?09/18 15:51

27^F推profyang:喔...所以光柵那些刻痕算是無限多光源就對了...09/18 16:12

請問時空扭曲

2^F→profyang:關於因果論...有人用"平行宇宙"解釋...但這都只是說說而09/17 19:41

3^F→profyang:已...09/17 19:43

6^F推profyang:費曼自己是天才，所以他的普物也...08/31 22:04

7^F→profyang:個人建議是當大一普物參考書08/31 22:05

[題目] 波滋曼分佈

[ Physics ]7 留言, 推噓總分: +3

作者: acceleration - 發表於 2007/08/27 16:20(18年前)

1^F推profyang:我覺得是由c正比於e^(G/kT)來的，就是波茲曼分佈的原形..08/27 20:46

2^F→profyang:至於波茲曼分部的證明要用到簡併態、乘數法則...請參考統08/27 20:48

3^F→profyang:計力學相關書籍....08/27 20:50

7^F推profyang:嗯...它用到史德齡近似:lnN!~NlnN-N08/28 22:33

[問題] 熱力學(?)疑問

2^F→profyang:推樓上，其實你只要想臭酸和冷卻得快不快並沒有關係...09/04 17:21
