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. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.38.14.42

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