Web3 de jun. de 2016 · 1. So an amplitude in terms of an electromagnetic wave is related to its intensity. So technically, the more intense a light wave is at a point, the more its amplitude. What is the intensity Intensity is inversely proportional to the A^2 of a wave. If you know the intensity, then the amplitude can be found using this formula I=1/2*p v w*A^2 ... Web8 de nov. de 2024 · The wave equation included physical constants from both electricity and magnetism, and extracting the wave speed from this equation resulted in a number …
