But with new techniques, some scientists have begun using sound to physically move objects. At that spot, the amplitude is zero, so there is no sound. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. here, even though the light was emitted down here. But the technique shows a lot of promise.
