So, we need to revive this topic.
Guys, yesterday I watched an episode of Stargate that described a civilization of creatures invisible to the human eye. As I understood the explanation, this is because the light reflected from them is out of phase with the light that the human eye perceives, and that's why we don't see them. So, how possible is this, and what did I misunderstand from that explanation?
That's because you need to emit a bundle of waves... complete invisibility won't work; the range is large enough for visible light. The object itself needs to be monochromatic, or somehow change the reflection and refraction coefficients.
That's interesting too.
Although, in my opinion, the easiest way is either to play around with reflection and refraction, or, as someone suggested, to transmit the image using a camera.
But they don't say what technology they use to hide all the Noxes, and just now Hathor has snuck away, those scoundrels :(
Actually, I haven't heard that the human eye perceives any phases... It generally detects the frequency of vibrations.
Well, it actually detects the amplitude. And the amplitude can change sharply during interference. However, interference with white light is a complex phenomenon.
More precisely, it detects the amplitude (brightness) and frequency (color). But a zero amplitude doesn't mean invisibility; it just means black color. ;) For invisibility, you need transparency.
