Question: A plane electromagnetic wave with frequency f = 205 kHz propagates in a vacuum in the positive y-axis with its electric field oriented along the z-axis. The amplitude of the electric field is Emaz = 10.0 V/m. We choose a start time such that at t = 0s the electric field is zero at the origin and we represent the oscillating electric field by: E(y, t) = A sin(ky – wt + 6). Part 1) Calculate the: Amplitude A = V/m Angular frequency w = rad/s -1 Wave numberk = Phase o = rad Part 2) Using your values from part 1, calculate the electric field components of this electromagnetic wave at y = 4.51 m and t = 1.52 s. E = Î+ |k V/m Part 3) Now calculate the magnetic field components of this electromagnetic wave at y = 4.51 m and t = 1.52 s- k T
