We were watching a light show that had a bunch of spotlights the other night (Ocean Cay lighthouse show if anyone is curious). The four beams on the right side of the lighthouse (as seen in the photo) just suddenly ended after some distance as shown in the second photo. What causes this? I would have expected the light to fade gradually to nothing.
Note that it looked exactly like this to the naked eye — the phone did a fantastic job of capturing what I was seeing.
Sorry – I couldn’t figure out how to post these directly to this sub, but it requires a visual depiction to understand – here are the pics:

A beam of light is only visible when it bounces off something into your eyes. Some of the light was bouncing off some fog into your eye. Once the light got past the fog, there wasn’t anything for it to bounce off of, so you couldn’t see it.
