OK here s a question
we hear things by the movement of sound waves, so if someone claps their hands it creates sound waves that travel to our ears, our ears act like small microphones and we hear the sound in our brain.
my question is, how do these sound waves travel through a door or a wall ?
keyhole obviously
and a wall if you left the door open
Is that serious question nimrod?
Riding the waves baby! 8)
Solid objects aren't always solid...
I'm feeling like good vibrations!
Are they giving you excitations?

I try not to be serious about anything these days ludo mate, except when it comes to paying rates & tax
Lol.
Thought as much, it was too stupid to be serious.

maybe stupid to a clever chap like you ludo but Im pretty thick so I had to google it, I mean light waves cant get through a wall so why can sound ?
What the fook are we on about here
Ok. Perhaps it's not such a stupid question. It's a bit like comparing apples and oranges.
Light is made up of little packages of energy called photons which actually move along the length of the light wave and as such are more easily reflected by solid objects. That's why we can see things, as the light hits an object some of it's energy is reflected into our eyes giving us colour.
A sound wave is basically a vibration, a sound 'particle' doesn't travel along a wave. A bit like flicking the end of a rope and watching the waves pass along it. This allows more sound the 'vibrate' it's way though more solid objects.
If one was built large enough, could an aircraft take off on a treadmil?
Yeah, why not.

Why is asking a question stupid?
