3.3.1.1 - Progressive Waves. A progressive wave transfers energy without transferring material and is made up of particles of a medium (or field) oscillating e.g. water waves are made of water particles moving up and down.
The total energy associated with a wavelength is the sum of the potential energy and the kinetic energy. The average rate of energy transfer associated with a wave is called its power, which is total energy divided by the time it takes to transfer the energy.

24 Ιουν 2024 · Mathematical expressions describe wave energy, power, and intensity. These formulas help us quantify how waves transport energy and how it changes with distance from the source. Understanding these concepts is key to grasping wave mechanics and their real-world applications. Energy and Power of Waves Energy transport in waves
Lecture 10: Energy and Power in Waves. Energy in a string. The kinetic energy of a mass m with velocity v is 2mv2. Thus if we have a oscillating wave in a string, the kinetic energy of each individual bit of the string is. KE = 1 mv2 = 2. (μ∆x) ∂A(x, t) 2. ∂t. (1) Thus the kinetic energy per unit length is. KE 1. = μ. length 2. ∂A(x, t) 2. ∂t. (2)
