Standing wave

Interference between two waves traveling in opposite directions (green and cyan) in a string whose ends are both fixed produce a standing wave (yellow). This is the fourth mode of vibration, with 2 wavelength
across the string. For more physics animations, please visit http://web.ncf.ca/ch865/

is the yellow one composition of the others???

[PelletierPhysics]

The yellow wave is the addition of the two other waves (superposition principle).

thanks! finally understand what it means when they say between nodes are half a wave length and stuff. =))

Challenge to people knowledgeable about standing waves... what did I capture in this 12-string guitar video that used a canon 7d hight speed shutter video, with similar effect... check it out by clicking me name or searching "magic guitar strings video high speed shutter"

@LiquidChem If you listen to a "standing wave," you'll notice beats. Basically, the amplitude of the sound goes up and down, but the frequency remain the same.

「波長、振幅が等しい二つの波が、【互いに逆向きに】同じ速さで­進んで」ゆくというのを明瞭に通時的に可視化してくれたおかげで­やっと正確に理解できました。

Thank you very much.

dude....you MUST make MORE OF THESE VIDEOS......im tired of learning theory and not being able to visualize.....

Godspeed

thanks so much : )

¿Is it the same effect that produced between tow near frequencys? Like when tunning a guitar i mean.

Sorry for my spelling

MEGA_AWESUME!!!!! Finally the stuff I've been searching for :D

[LiquidChem]

how can this be translated into audio? what would be the result, does the third line then represent another tone? is this harmonics? I created a sinve wave, then reversed it, and combined the 2. what happened - the signal was the same but much lower amplitude, thus quieter. Is this the same thing? it doesnt seem like it. The third line would have to be a negative value.. Does anyone know what Im trying to ask

This a 4 loop standing wave but how is a 1 loop standing wave created?

OMG i cant believe a 10 second video helped me so much
