: If i have two light-source, A and B. : A send light C1 and B send light C2.

: B.....C2.....C1.....A

: What happens when light meets?

: B.......C3........A.

: C1+C2 join together, and result is C3.

: What is speed of C3?

what do you mean, what is the speed of C3?

If i understand what your asking, your saying that when two light beams are aimed at eachother and they meet; what is the speed at the meeting point?

the speed of two passing beams is irrelevant. however, it is more interesting to note that the observed velocity of light passing by, while traveling the opposite direction, (at or near the speed of light), will appear that the light passing by me is not the sum of my velocity and the light passing. But rather the light passing by would appear the normal velocity of lightspeed. This is relativity.
