Proceeding from Maxwell's equation shown that in the case of a plane electromagnetic wave ( figure ) propagating in vacuum the following relations hold :(deltaE)/(deltat)=-c^(2)(deltaB)/( deltax), (deltaB)/(deltat)-( deltaE)/( deltax).

Answer»

Solution :`VEC(E)=hat(j) E(t,x)`
`vec(B)=hat k B (t_(1),x)`
and Curl`vec(E)=hat(k) (deltaE)/( deltax)=-( delta vec(B))/( deltat)=-hat(k)(DELTAB)/( deltat)`
so `-(deltaE)/(deltax)=(deltaB)/(deltat)`
Also Curl`vec(B)= epsilon_(0)mu_(0)(delta vec(E))/(deltat)=(1)/(C^(2))(deltavec(E))/(delta t)`
and Curl`vec(B)=-hat(j) (deltaB)/(deltax)` so `(deltaB)/(deltax)=-(1)/(c^(2))(deltaE)/( deltat).`
