    Intensity of electromagnetic wave is defined as the energy crossing per second per unit area perpendicular to the direction of propagation of electromagnetic waves. 

    The intensity of electromagnetic wave at a point is
                          
    where ,
                 

    and c is the velocity of electromagnetic wave. 

                      
    Here E0 and B0 are maximum values of electric field and magnetic field respectively.
