an observerA stands on the ground with clock Ca and an observer B sits on
an airplane with cllock Cb. the airplane moves with a velocity v with respect
to the ground. 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.

1F：→ r19891011:我猜是(a) 05/29 23:21
2F：→ r19891011:Δt'(等速運動的時間間隔)=γΔt(相對靜止時的時間間隔) 05/29 23:26
3F：→ r19891011:是1/γ才對(囧) γ=(1-β^2)^(-1/2)>1 ,β=v/c<1 05/29 23:28
