Prove that average energy density of the oscillating electric field is equal to that of oscillating magnetic field.

Show that average electric evergy density (u_E) of electic field is equal to average magnetic energy density (u_E) of magnetic field in electro magnetic wave.

Show that the electric field intensity at a point in an electric field is equal to the negative of the potential gradient of the field at that point. E = -(dV)/(dr)

In an electromagnetic wave,the amplitude of oscillating magnetic field is 2 xx 10^(-7) T. What is the amplitude of oscillating electric field in the wave?Given c=3 xx 10^8 m s^(-1) .

Show that the total energy of the electromagnetic wave is equally divided between the electric and magnetic fields.

In what way is an electric field different from a magnetic field?

How is electromagnetic wave produced? Draw a sketch of a plane electromagnetic wave propagating along x-axis depicting the directions of the oscillating electric and magnetic field.
