其實有d問題係我見人地問,我自己又唔識,所以先起度問下~
我自己就冇睇過beyond 2000 ,連本書都冇,係人地講 [表情]

我有........但冇睇過

我nee個問題黎自joint us 85 年第20題MC ge solution ,果度答案應該係錯ge ~

85年........

joint us 85 年第20題MC ge solution


我覺得冇錯喎...................

unpolarized solution 話唔岩, 係partially polarized
不過partially polarized 都可以叫做unpolarized ga ma~ solution 唔可以夾硬分開佢地~話佢地完全唔同~
反而另一句statement , reflected and refracted wavefronts perpendicular to each other 就有問題 , 應該係佢地ge rays perpendicular to each other

係架..........!? @@

我係分做completely polarized ,partially polarized ,unpolarized
unpolarized 我當係完全冇polarized....

呢句唔可以話係錯ge.....
因為本身wavefronts就係perpendicular to rays ga la

若果rays 係perpendicular to each other ge話，
咁wavefronts都係ge姐.....

不過話wavefronts perpendicular係有d怪lor........

.......

reflected ray 都可以話係partially polarized 同 completely polarized , 2個都冇問題

都可以甘講, 我諗另一個解釋係條refracted ray 係起好多方向transfer 緊 , 所以wavefront 都唔止一個, 所以 reflected ray係horizontally polarized ,佢ge wavefront 唔可以話同另一條起好多個方向transfer ge ray ge wavefront perpendicular , 我諗所以甘用wavefront nee 個字眼先有問題

out topic 一問....

考chem o既考成點................??

paper1 好唔掂啊..................好多唔識....
paper2 都還可以...............

paper 1 唔多掂~好多唔識, 冇溫p-block , essay 就....... , 其他寫就寫左唔少野,不過岩ge %應該唔高
paper 2 even worse . part A 希望有一半分la , part B 2題加埋有10分都好開心~

overall 合唔合格都要30/6 先知

你好...我係教育學院學生...視藝系 ..現正做緊一份關於八卦鏡研究的assignment.....請大家利用一分中以內的時間.....幫幫本人填問卷....十十十萬火急......唔該晒唔該晒.....http://www.my3q.com/home2/103/seyidonna/7365.phtml

你.....唔洗個個topic都post ar ma......

係急ge就去吹水版開topic la~
呢到都冇人ge~

呢條equation係咪out syll. ga la?

1/f=1/u+1/v

(optic)

好似係,我未用過呢條式

見過solution 用黎證一d野, 而家應該唔用ga la
