the most popular example of something that's invisible is air. right? but air is not invisable. if air was truely invisible, sunsets and sunrises would have no color. you would be able to see stars during the day. the reason we can't is because light is reflecting off particles in the atmosphere making the sky appear blue instead of black. it makes the sunset colorful. so therefore, air cannot be invisible.
what is invisible? you can't see it? well if you were in a room with no windows, and you shut off the lights, and unplugged the clock and everything that gives off light and were sitting in pure darkness, are the walls invisible? you can't see them so they must be. but we know that a wall of a room can't be invisible. so does invisible mean you can't see it even if there's light shining on it? well this isn't the case with our sky, because when light shines on it, you can see it. you see blue. or reds in a sunset. so air is not invisible. you just can't see air in small scale
