# E-M wave propagation through free space # Energy associated with E.M wave Electric energy density (Ue): Ue = (1/2) * (Ē dot Ē) Magnetic energy density (Um): Um = (1/2) * (𝐵 dot 𝐵) / μ₀ Total electromagnetic (EM) energy density: Uem = (1/2) * (ε₀ * Ē² + 𝐵²/μ₀) # Photon associated particle E.M. waves have associated energy, momentum (linear & angular), but it doesn't associated charge & current. Additional Notes: The image is well-organized with clear headings and subheadings. The handwriting is legible, making it easy to read and understand the content. The equations are written accurately and consistently. Equations: Ē = (î + ĵ)E₀ * exp(i(ωt - 𝑘 ∙ 𝑟)) 𝐵 = (î - ĵ - 𝑘)B₀ * exp(i(ωt - 𝑘 ∙ 𝑟)) 𝑇 = <Ē × 𝐵> = (E₀B₀ / (2μ₀)) * (-î + ĵ - 2𝑘) |𝑇| = c |Ē| = c B₀ = (3 / (2μ₀)) * (E₀ / c) Equations: Ē = 𝑘̂E₀cos(ωt - 𝑘 ∙ 𝑟) Planes: -4x + 3y = 0 Average power:

= ∫(𝑆 dot dA) Unit vector normal to the plane: 𝑛̂ = (4/5)î + (3/5)ĵ 𝑃 = (1/5)ε₀cE₀² Additional Notes: The image is well-organized with equations grouped together. The handwriting is legible, making it easy to read and understand the content. The equations are written accurately and consistently.
