| May 14 at 15:16 | comment | added | Ivan Nepomnyashchikh | This explains what I couldn't understand. Here are my remarks for others like me. The author of the post asked to explain why a wave can be described by a complex function. I had the same question. My thinking was along the following lines. A real physical wave (a water wave for instance) is, experimentally, a sin wave, let's assume. How is it sin a complex number I wandered? The answer is that we don't measure the wave as a sin. We derive a math equation for the wave, solve it, get the complex function as the result of the solution and, for real physical wave, we keep only the real part. | |
