P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string.
WebSep 12, 2024 · We now consider solutions to Equation 16.3.8 in the form of plane waves for the electric field: Ey(x, t) = E0cos(kx − ωt). We have arbitrarily taken the wave to be traveling in the +x -direction and chosen its phase so that the maximum field strength occurs at the origin at time t = 0. WebThe Poynting vector is not the energy (density) in the electromagnetic fields, which would have units of J m$^{-3}$, it is the flux of energy per unit time with units of W m$^{-2}$. That the Poynting vector is (instantaneously) zero tells you that there is (instantaneously) no flux of energy per unit time carried by the electromagnetic fields.
WebIn physics, the Poynting vector (or Umov–Poynting vector) represents the directional energy flux (the energy transfer per unit area per unit time) or power flow of an …
