How are you? I am trying to create an animation which I’ll use during a Powerpoint presentation about ultrasound physics however I am quite inexperienced with Blender. The idea is to animate sound waves, which will hit an object and reflect back. I’ve created a nurbs surface and duplicated it three times, placed them equidistantly from each other (this represents an ultrasound pulse, consisting of three waves). A box is used as the target object. Here’s the basic scene:
The sound waves propagate at a fixed speed, so their distance won’t change while they are travelling, but when the first wave hits the object, it hast to rotate 180 degrees and travel back. The second and thrid waves should follow the first wave. Now, I can animate the waves until the first wave reaches the object but then things get complicated for me. Do I need to manually animate the position for each of the waves separately? Is there a way to animate the first wave and copy the animation to the second and third waves? Is there a better way or a way to automate?
