Anyone ever think of casting out some lasers over your city @ night to give the illusion that a UFO is in the sky?
Here:
Assume I have a laser in my hand. I point the laser up to the ceiling. What do you see? A dot, correct? Well, what if I take my hand & start spinning it around in a circular motion. Now what do you see on the ceiling? A circle. Why? Persistence of vision.
^Wait a second. Wouldn't I give an illusion of a persistant circle all the way from the tip of the laser to it's stopping point, which in this case would be the ceiling? So instead of just seeing a circle on the ceiling, I would see a cylindicular shape from the tip of the laser to the ceiling. -Is that correct? I do not have a laser on hand to test out.
Regardless of whether I'd see a solid cylinder of light OR just a circle on the ceiling, could this be replicated outside?
It can't be, correct? I mean, beams are infinite right? Therefore, the only illusion I'd give is from the tip of the laser to infinite
^See, that's the issue. If I were standing in my driveway, & shooting out a laser into the sky & making it "go round," you wouldn't see a "circle" or "UFO" in the sky. All you would see is circles from the tip of my laser to infinite.
Okay, this is going to sound extremely abstract, but I'm new to lasers & lol I'm not very old either.
Colors are rated by frequency, specifically by nM.
Assume:
Red Paint + Blue Paint.
If you mix those two together in a 1:1 ratio, you will get purple paint.
I don't understand. Red is approximately 650nm & blue is approximately 475nm. How do we go from 650nm & 475nm to get 400nm, which is roughly purple or violet.
650 + 475 =1125
1125/2 = 562.5, therefore 562.5 is your average "nanometer"
562.5 is NOT violet. That's like yellowish/greenish
What I am getting at is "Does frequency change when you mix colors?" Let's assume frequency does change, & in this case, it can go up in total frequency.
Here's an example:
I have a UV laser pointer in each hand.
Assume I point these two lasers at a wall 30 ft in front of me. The lasers are NOT touching.
Now, what if I converge these lasers together at 30ft. Assume frequency doubles & you're now seeing visible light or in this case, a laser dot.
...I beamed two UV lasers out at a wall. UV is invisible to the naked eye. BUT, when I converged the two beams, I now created something that the naked eye can see!
Notice what I am getting at? I just created a "starting point" for a laser.
I understand ^ is all pretty abstract, but it's to help make a point. So, is there a way to start & stop a laser beam? I just posted an abstract way to "start" a laser by converging two laser beams at a given distance. hmm, lol they've figured out how to bend light. I sure hope there's a possible way to stop & start a laser lol
