So if that's true then why can't we see an airplane before we hear the sound? Explain this to me LadyShea without weaseling as you are constantly accusing me of doing. |
We can absolutely see a plane before we hear the sound if we are looking at the planes flight path at the moment it comes into view. If you know where and when to look, you will see it first, every time.
If we aren't looking at the sky or don't know exactly where to look, we would probably hear the sound first. |
That is not true LadyShea. We hear planes before we ever see them, even if we know where to look. You are wrong. |
You are wrong, not me. Demonstrably wrong. I spent my summers near the Naval weapons testing center and saw jets every day, I grew up outside the Air Force Academy and so have seen the Thunderbirds many times, lived in the flight path of one of the busiest airports in the world for over a decade, and have seen the Blue Angels fly as well. Planes can even fly faster than sound travels, so even without the speed of light being the factor it is, you could easily see them before you hear them in many circumstances. |
If the plane is reflecting light, we should see airplanes at far distances before we ever hear them in every single circumstance.

Isn't that the point I'm making? If light is traveling so fast, altitude wouldn't even be a factor. The light would be traveling so fast that it would strike our eyes before the sound strikes our ears, but this is not what occurs. The reason we hear the airplane and don't see it is because the airplane is too far away, or is out of our visual range because it's too small to be seen at that distance.

I'm not talking about obstructions where it's obvious that we wouldn't be able to see the source. I'm talking about a clear path to our eyes, and we still hear the sound before we see where the source of the sound is coming from. |
So you have reset all the way back to not understanding what resolution is.
Goddamn, don't you get tired of making the same stupid mistake over and over and sounding like a moron?
If a plane is too far away for our eyes to resolve the image, we can't see it....remember? Resolution has nothing to do with the speed of light. Sometimes we cannot see the plane because it is too far away to resolve (altitude is distance too, you know). |
Frankly if it's too far away to resolve, we can't hear a jet engine. So I'm willing to say: we
always, in every circumstance, can see planes before we hear them, given a clear unobstructed view.
I've no idea why peacegirl is even arguing this way around; surely if she was arguing for her position, she'd say we can see planes first because vision is instant?
The crazy world of peacegirl...
