The electric field associated with an electromagnetic wave propagating in free space is given as: e-e, cos(kz-ot)1+e, cos kz +0t)} the average energy carried by..please answer this

@Bhavnesh , can you please write Electric field expression in paper? by the way, the process is (1) first obtaining magnetic field (B) by relation [ B= K k cap× E vector/ w]..then (2) obtain S=E× B/ mu not ...(3) Then taking average of S... because represents average Energy

here it is
