[領域]相對論 (題目相關領域) [來源]極想知道解答的作業題目(很怕教授不檢討><) (課本習題、考古題、參考書...) [題目] When O' is passing O with speed v,an explosion occurs at point P(x)in frame O.If the explosion emits a particle with speed u, then it arrives at O at a later time t=x/u. (a) In frame O, when will O' detect the particle? (b)In frame O', when will O' detect the particle? (c) In frame O', where does the explosion occur, P'(x'=?) (d)If you subtract from answer (b) the time for the particle to travel from P'(x') to O' in frame O', you would get the time t' at which the explosion occurs as observed by O'. Please do so and what is your answer? 其實題目本來有圖,但抱歉我不知道怎麼弄上來>< 是說照著題目敘述應該沒有圖部會差太多... 這題我想超久但始終不太確定解題的邏輯,拜託各位幫忙了m(_ _)m [瓶頸] (寫寫自己的想法，方便大家為你解答) 我在勞倫茲轉換這裡卡了很久... 而且事實上我自己也不知道這題要不要用勞倫茲轉換 或是為什麼要用勞倫茲轉換... 感覺我好像是再被題目而沒有真正了解相對論的意涵QQ 拜託大家了>< --
