And what do you think that speed is?

Wait, I thought sound and light were supposedly the same thing in cellworld? Yet one is instantaneous and one has speed?

Difference in sensitivity between the eyes and ears. Ears are git slow.

Probably.

It all depends on what rebounds back to the source or what hits the source directly.
Ok I'll take that as you can't describe what moves in a lightbulb

Take it how you want.
Ooh touchy, just cos you can't explain how a lightbulb's moving parts work, eventhough it was you that said it had moving parts

If you think the filament works without any movement through it then you go with that.
What is moving? Is it the same thing as in an led?

Matter is what is being pushed through it.
If you want to go down the atoms route or electrons or molecules or whatever, it's fine.
I'll just call it matter and it covers everything.
Matter in solids or matter through gases/fluids/liquids.

Why do you need a rebound for sound to have a speed? A sender and a receiver X distance apart in average atmospheric conditions, nothing between, roughly what would the speed of sound be between the two?

To gauge it.
You can't gauge speed if you don't have something to hit off.
However many seconds it takes from energy push to impact.

Not entirely sure I agree with that, but lets go with it.
Ok, say you have a standard interior house wall, plaster covering bricks, and you position your sound source 4m from that wall. The sound bounces back to the sender, what is the speed of sound in those circumstances?

It depends on the pressure and frequency of it.
It's all dependent of pressure and frequency from sender to receiver.

There's rather a lot he doesn't know tbhChrist, he doesn't even know the difference between speed and time.
Reluctant to put a number on it because that would be listening to the story tellers.Christ, he doesn't even know the difference between speed and time.

You seem reluctant to give even a vague figure, which is surprising given your experiments.
The given figure is around 330 m/s, but it does change with temperature and pressure. Do you accept that for most cases it is around that?
