QuestionQ4: The figure illustrates an electromagnetic wave at t=0t=0. Which equation correctly describes the wave? a) Bz=Bsin(kx+ωt)B_{z}=B \sin (k x+\omega t) b) By=B0cos(kzωt)B_{y}=B_{0} \cos (k z-\omega t) c) Bz=B0sin(kyωt)B_{z}=B_{0} \sin (k y-\omega t) d) By=B0cos(kx+ωt)B_{y}=B_{0} \cos (k x+\omega t) e) By=B0sin(kzωt)B_{y}=B_{0} \sin (k z-\omega t) f) Bz=B0cos(ky+ωt)B_{z}=B_{0} \cos (k y+\omega t)

Studdy Solution
Choose the equation that correctly describes the wave based on its propagation direction and orientation. Without the figure, we cannot determine the correct option, but the process involves matching the wave's direction and field orientation with the given equations.
