- Does a metre rod at rest relative to K appear longer or shorter in respect to K'?
I have to admit that my "best" math days are long gone. That said, I wonder if anyone can help me? I'm stuck in part 1 of Einstein's book on 'Relativity, The Special & General Theory: The behaviour of measuring rods & clocks in motion', specifically on the second equation : √(1-v^2/c^2) used to describe the length of a metre rod at rest on the x-axis in respect to K as viewed from K'. By substituting the value of x with 0 & 1 respectively and getting the difference
, I calculated the relative length of the metre rod as viewed from K' to be the reciprocal of the above equation i.e.: 1/(√(1-v^2/c^2)) meaning the metre rod would appear longer instead of shorter as viewed from K'. Where am I going wrong?
