Standing waves can be created by vibrating a string fixed at both ends •If you vibrate the string at one of its 'special' (i.e. resonant) frequencies, the wave doesn't propagate; rather it just sits there vibrating up & down in place ©https://www.youtube.com/watch?v=cnH2ltfW48U …pic.twitter.com/N166Xk2wAH
Standing waves are nothing more than a consequence of superposition
•When the sine wave sent in from the left gets reflected off the pole on the right, the reflected wave is π out of phase with the incoming wave
Adding these two signals together results in a standing wavepic.twitter.com/yMGdhLXrPM
These waves can represent the energies of a quantum harmonic oscillator for odd n.pic.twitter.com/zs3AuUFs7g
But the eigenstates of a SHO have a Gaussian envelope
