if this continues can it be described using logs?

I personally have no ******* idea. I just felt bad that nobody responded to your question.

Wow I've always wondered about this. This will save me lots of time to think about other stuff now. Thank you! What about particles in air though - or are there too many factors such as pressure / wind etc to visualize it? scienceexplain / sciencexplain pls halp.

the first one (Longitudinal waves), where there are two particles colored red, so you can see what happens to them. In a closed system, the particles actually remain in the same place. if this were an open system, you would see the exact same thing as in the content, except without the up and down motion i.e., it would go forward, back a little, then forward again, etc.

I don't understand any of it, but it's interesting

By this logic the buoyancy is much more powerfull on the tops of waves due to the compressed particles. Very intelesting!

yes, very inteLesting.
seriously dude, how do you manage to press l instead of r?

the particles move to the right because in a addition to being a wave, this is also a current. A normal wave, i.e. one made by dropping a stone in the water, would not move particles on the surface.
All normal surface waves (non-current) can be written as combinations of sinus functions, and they oscillate back and forth.

I was always taught that particles in a wave oscillate back and forth on a constant origin, similar to how this .gif shows it, but I could be wrong considering I've only studied up to calculus based physics section 2, which would be the electro-magnetics classes.

forgot the .gif of a wave propagating through water.

Can someone explain to me how undertow works? I live by the sea but I don't know why I should stay out of the harbour inlet

Pretty much. Sometimes it can drag you out far enough while disorienting you so you don't know which direction the shore is in. There are also times when the rip tide actually prevents you from swimming back to shore by just pulling you back out. A decent amount of people drown simply from exhaustion from trying to get back to the shore. If snagged you are supposed to swim almost parallel to the shore while slowly coming in. It's meant to find an area without a rip tide giving you a chance to get to the shore.

no really it moves when the water moves?

**** I would never in a million years figgure that out

seriously why is this here?
User avatar #60 to #52 - krizz (04/29/2014) [-]
there wasn't much current tho

Maybe someone can help me out here. If you take a point at the top of the wave, it appears that it is advancing in the wave's direction, in the long run. Therefore, how can someone get ''carried away'' by the waves AWAY from shore?

******* maths and physics. Beautiful things.

So during tsunamis the best course of action is to get below the ******* wave.

No **** .

Water can stay for about a century in just the mesopelagic zone. I wonder how long it is for water in deep sea trenches.

I vaguely remember learning that particles don't travel with waves

And this is why it's so damn hard to render a full realistic ocean on a computer
