Question Suppose an inertial frame of reference S’ moves at a constant velocity v in the positive x-direction with respect to a second inertial frame S. The Lorentz transformation from S to S’ for the x coordinate of displacement is given by: x′ =γ (x − vt) Write down a corresponding expression for the inverse transformation, i.e. from S’ to S, giving x in terms of x’ and t’. Use these two expressions to derive the Lorentz transformation equation for time: t'=γ(t-vx/c^2) I think I have the first part, I answered x =γ (x' + vt). But the second part I have no idea I have been looking online and even watching lectures on youtube. Thanks in advance.
