Transverse and Longitudinal Waves

[OXSultanXO]

I like that part when the wave moves

[schnouttz]

In 6 seconds, you just did what a half hour physics explination could not.

[fctapes]

YES

!

[Kiriha15]

for 30 min my physics professor was trying to explain this. :<

[mrg3]

@Kiriha15 Did the video clip help you?

[Kiriha15]

@mrg3 of course :D

[EnzoWTF]

Wait, is my Youtube just f*cked up, or is there no 0:06 :D

i have a question that I desperately need need an answer to. When you make a transverse wave in a slikny, does the reflected wave have a lower speed than the incident wave?

[mrg3]

@im2013026 What should the wave sped depend upon? In the usual model, the speed depends upon the tension and the mass per unit length of the slinky. Is there anything in those ingredients that could depend upon whether the wave was reflected or not?

[TeslaBlueRepublic]

@im2013026 The transverse, reflected, indirect wave is exponentially slower than the the longitudinal wave. Imagine a broomstick 5 yards long and situated against my head. For a transverse wave, you shake it - I will see the energy before it gets to me. In slow motion the pole would look like a snake - a sinusoidal wave.

For a longitudinal wave, you pound the end of that broomstick with a hammer. No delay, instant pressure/power. Longitudinal waves exceed light speed.

boom goes the dynamite

[Tynkywinky]

Very cool waves

[pattitsai]

Good job!

[76mrlonely]

Thanks...textbooks sucks ass...to learn physics..you have to feel physics..and not just read the fucking textbook...

[captnbrimster]

:) Thanks!

[avenged7xguitar]

What?

[A1eXIzNotPr0]

Thanks. This helps me with my homework. If only I watched this before the test :(

[misbahuddinathar]

could have been better if a wave train was animated, just a single pulse doesnt give a clear idea of further things

[mrg3]

@misbahuddinathar ,There is a companion video with harmonic waves.

[mymsong]

oh shiiiiiiiiiiiiit, now i get it :D

[GTSRBOY]

Shouldn't the rarefaction be behind the condensed part on the longitudinal wave?

[noursafaa]

very interesting thnx

[MrMasterDEvil]

totally awesome explanation! =D

[samhume123]

You sir, are a genious.

[J3ofHearts]

i am so dumb, but i still don't get it :/

[mrg3]

@J3ofHearts  For transverse waves the disturbance (in this case the displacement of the slinky) is PERPENDICULAR to the direction the wave is moving (in this case along the slinky). For Longitudinal waves the disturbance is ALONG the direction the wave is moving. In some materials these two waves go at different speeds, and in fluids (liquids or gases) transverse sound waves don't go at all! (This is important for earthquake vibrations going through the earth's core).

[J3ofHearts]

@mrg3

ah yes, that makes it more clear, thank you very much!

[Beedletwix]

Thanks!! Just what I needed to understand.

[malekmoesousousamir]

simple and almost best describing!

[Pinkpolkadotcats]

whoa! thanks so much. exactly what I needed to better understand my physics homework. :-)

[PFJT]

thanks

[mbordo2]

this should help with my physics final..thx

[lxmcflysxgirl]

I would like to have this video in my presentation. Do you mind if I could borrow? How could I get this video?

[addieroxrev09]

finished before it loaded. ! anyway great animation

[xfxaxnxgx]

Thank you sooo much.

[mikayla0567]

OMG that's what I wanted! I couldnt even find something like this from Google! Thanx!

[swimRYANLOCHTEfan413]

thank you soo much exactly what i needed to study

[kamyarghofrani]

exacly what i was looking for

[markgilbert1]

This does fit the empirical observation. The only requirement of a valid scientific theory.

Experimentation is the further testing of theory against empirical observation.

Some people believe that multiple theories can not match empirical observation. THAT IS PSEUDO-SCIENCE.

Some people believe that you can disprove a theory with another theory. THAT IS ALSO PSEUDO-SCIENCE.

The only scientific method of disproving a theory is by empirical observation.

[ActiveStorage]

well said

[Pierrotzin]

Great  ! Thx

[mazenteacher]

i have taken what i am in need of...

thank you...

[lamprac]

are scalar and the equation that you say this is waves are physical phenomena that define time-varying fields that spread in space with finite speed. The equation is waves

[lamprac]

yes tesla created and manipulated em standing waves, it allows to create scalar waves the way haarp does.

shalom.

[boxa888]

whats a shal om???

[FuseBox80A]

boxa888, does those waves exist in electromagnetism?

...the ... theory ... restores the medium [luminiferous ether] ... and certifies that the vibrations are transverse, and that the velocity is that of light. With regard to normal [longitudinal] vibrations, the electromagnetic theory does not allow of their transmission... -Maxwell

Or does it?

[boxa888]

i put up some calculations if your interested in tesla's wave theories. yes they do go faster than light, and do contain industrial energy which is held in the earth for "tapping" it for use.i am not sure what they really are, they are not hertzian! tesla sayes this multiple times, to find the speed tesla used basic trigonomic functions for the speed and later found the speed faster than light, thus we can send energy and data faster than light!!!

[xilence007]

good simple example of longitudinal wave and transverse wave

[boxa888]

yess telsas scalar waves and regualr em energy

[DelaCaseas00]

awesome video. could use so sound though. might i suggest Go Dj by Lil Wayne.
