[领域]相对论 (题目相关领域) [来源]极想知道解答的作业题目(很怕教授不检讨><) (课本习题、考古题、参考书...) [题目] 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? 其实题目本来有图,但抱歉我不知道怎麽弄上来>< 是说照着题目叙述应该没有图部会差太多... 这题我想超久但始终不太确定解题的逻辑,拜托各位帮忙了m(_ _)m [瓶颈] (写写自己的想法，方便大家为你解答) 我在劳伦兹转换这里卡了很久... 而且事实上我自己也不知道这题要不要用劳伦兹转换 或是为什麽要用劳伦兹转换... 感觉我好像是再被题目而没有真正了解相对论的意涵QQ 拜托大家了>< --
