State Maxwellβs equation for the curl of the magnetic and the electric field in free space. State the meaning of all the terms in the equations and identify the displacement current density. Using Maxwellβs equations, derive the wave equations for B. Show that the wave equations admit plane waves for the electric and magnetic fields in free space of the form π¬ = π¬ππ π(ππ§βππ‘) , π© = π©ππ π(ππ§βππ‘) where π¬π and π©π are constant vectors with real components if π 2 = π 2π0π0. Show that E and B are transverse waves propagating with speed π = 3 Γ 10^8 ms-1 .
