Often to describe relativity is used example with two ships. Ship B is traveling at 0.5c speed from ship A. Ship A is standing still and shooting out beam of ligth in direction of ship B. Ship B has this light clock wich is placed verticaly. I understand the time delation with vertical clock thing can be calculated with formula. c^2=c(h)^2+c(v)^2 , where c-speed of light, c(h)- the speed of ship B=0.5c compared to shipA. c(v)- the speed of light in vertical direction compered to ship A. So c^2=0.25c^2+c(h)^2 -> c(h)=0.8666. So i undertand time delation factor is 0.86 or 1/0.86=1.16. The time for ship B i slowed down by 1.16 sek compered to A. But if th time delation facotr is 1.16 how can he see the passing light (of ship A) at c speed? time delation factor should be c/0.5c = 2. So hes time compered to ship should be slowed be 2 not by 1.16. So where i am wrong? Hope you undertand my question and what i have written. My head is boiling from these questions since im interested in these Einstein's theories.(adsbygoogle = window.adsbygoogle || []).push({});
