Homework Statement
In frame F there are two lights on the x-axis at D and -D (D=0.6x10^9 m ) which flash simultaneously when t=0. There is another frame F' which moves at v=0.8c in standard configuration with F.
I need to work out when observers standing at the origin of both frame F and F' will see the light flashes, and also in frame F' if the speed is -0.8c instead.
Homework Equations
[tex] x' = γ(x-vt) [/tex]
[tex] ct' = γ(ct - \frac{vx}{c}) [/tex]
The Attempt at a Solution
So I think for observers in frame F it will be 2 sec but I'm not sure how to work out when observers at the origin in frame F' will see the flashes. I've got the distance to both points in F' and the time the flashes take place in F' but I am not certain what to do with it.
