WebA wave is a disturbance that travels or propagates from the place where it was created. Waves transfer energy from one place to another, but they do not necessarily transfer any mass. Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through. Web2 de mar. de 2024 · Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That's why light is called Electromagnetic Radiation. …
What is the amplitude of a light wave? - Physics Stack Exchange
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 ...
