Question: An electromagnetic plane wave of wavelength 0.21 m travels in the positive x-direction in a vacuum. Calculate the magnitude of its wave vector k and its angular frequency w. k= m-1. [Input your answer as a number.] الي 3 = rads s-1. [Input your answer as a number.] At a certain position and time, the electric field of the wave is given by E = (2 x 105 2) V m-. Calculate the magnitude B of the magnetic field at the same position and time. B = T. [Input your answer as a number.] The magnetic field B at this position and time points in the direction of O-Z O+x O-X O+y O-y O+Z
