Homework Statement
In the inertial frame ##S'## the standard lattice clocks all emit a 'flash' at noon. Prove that in ##S##, this flash occurs on a plane orthogonal to the ##x##-axis and traveling in the positive ##x##-direction at speed ##\frac{c^2}{v}##.
Homework Equations
Lorentz Transformations: ##x' = \gamma(x-vt)## and ##t' = \gamma(t - \frac{vx}{c^2})##
The Attempt at a Solution
[/B]
The second part is relatively simple, set the flash to occur @ ##t' = 0## and then solve the corresponding Lorentz transformation equation to get ##\frac{dx}{dt} = \frac{c^2}{v}##. The part I don't understand is show to show that it's orthogonal to the ##x##-axis. I know you want to end up showing that ##dx = 0##, I just can't manage to manipulate the Lorentz equations to get it in that form.
