Relativity problem

1. A clock C is at rest at the spatial origin of an inertial frame S. A second clock
C′ is at rest at the spatial origin of an inertial frame S′ moving with constant speed u
relative to S. The clocks read t = t′ = 0 when the two spatial origins coincide.
When C′ reads t′
2 it receives a radio signal from C sent when C reads t1. Draw a
space-time diagram showing this process.
Determine the space-time coordinates (ct2, x2) in S of the point (event) at which C′
receives the radio signal. Hence show that
t1 = t′2[IMG]file:///C:\Users\KUMI\AppData\Local\Temp\msohtmlclip1\01\c lip_image002.gif[/IMG]

This sounds like a homework problem and we won't help you with homework until you take a crack at it yourself. In this case you wrongly tried to show us a GIF file and it may or may not be right. Please fix this problem. We'll then try it again when you do.
