We don’t see light until it’s reflected off something and depending on what the thing is, it absorbs some wavelengths and not others and that’s how we perceive colours. But why? How come we just don’t see all light all the time (when exposed to it)?
In: Physics
What? This question doesn’t make any sense. How would you see light that doesn’t enter your eyes? We see things with light. In order to see something, light that’s bounced off it has to reach our eyes? Essentially what you’re asking is “why can’t we see light with other light” which, again, doesn’t make sense.
