Consider the relativistic time dilation effectwhith one of t the following descriptions is correct???? (a) the observerA find that Ca counts faster than Cb, but the observer B finds that Cb counts faster than Ca. (b) the observerA find that Ca counts slower than Cb, but the observer B finds that Cb counts slower than Ca. 這兩個選項都有書去選 請問正確答案跟原因 THANKS. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.38.14.42

Δt'(等速運動的時間間隔)=γΔt(相對靜止時的時間間隔)

是1/γ才對(囧) γ=(1-β^2)^(-1/2)>1 ,β=v/c<1
