if two light rays start simultaneously in the space from exactly opposite ends in opposite direction that is separated by a distance of 600000 km in a way they meet at the mid point (300000 km from source) ; 1) how much time it will take to meet the front most photon of one ray to meet the front most photon of opposite ray and 2) what will be the speed of photon of the first ray relative to photon of other ray

If two light rays start simultaneously in the space from exactly opposite ends in opposite direction that is separated by a distance of 600000 km in a way they meet at the mid point (300000 km from source), then:

1. How much time it will take to meet the front most photon of one ray to meet the front most photon of opposite ray and

2. What will be the speed of photon of the first ray relative to photon of other ray?
