- jolmg 7y agoDid you see measurements somewhere or are you just estimating from the time counter and the speed of light?
- MattSteelblade 7y agoEstimating based on the time counter.
- SilasX 7y agoWait, the light is all incoherent before it passes the dotted line, then coherent until it bounces and passes back through? What's going on?
- aflag 7y agoYou have to remember that's scattered light.
- improv32 7y agoI believe the area between the dotted and solid lines is a mirror. The blob of light is visible because it's passing through some medium that scatters it, then when it disappears it has been absorbed by the mirror, then we see it reemitted shortly after.
- hcs 7y agoThe solid line is the mirror, the dotted line is the edge of the scattering medium. I assume there is air or vacuum in between.
