How does the detection mark for Pyke's Ghostwater Dive ability work?

I am playing Pyke, a champion in League of Legends. I need some clarity on one of his abilities called Ghostwater Dive. Here is a link to show it: Pkye ghostwater dive. Basically, the spell makes you invisible to enemies in a certain range and makes you move faster. Now the one thing that has me confused is something that is not said, when Pyke uses this the enemies close by get a mark around their bodies that tells them Pyke is invisible. I know this is a thing but it does not show it in the ability description. So my questions are:

1. What is the range of the mark that Pyke puts out?

2. If there is a range if I start outside the range then go into the range will the mark still appear on the enemies?
