2 . 015(part3of5)10.0points What are the directions of the instantaneous magnetic field and the instantaneous Poynt- ing vector respectively? 1. hatwide B = ˆ and hatwide S = ˆ ı
mittal (im5936) – EM waves and particles – yeazell – (58010) 7 in the ˆ ı direction, vector B must be in the ˆ k direc- tion. The Poynting vector is in the direction of propagation of the wave: ˆ ı . From the definition of the Poynting vector, vector S = 1 μ 0 vector E × vector B and ˆ × ˆ k = ˆ ı . 016(part4of5)10.0points What is the instantaneous value of the energy density of the electric field?
017(part5of5)10.0points What is the instantaneous value of the energy density of the magnetic field?
