In free space, the energy of electromagnetic wave in electric field is

{U_E}

and in magnetic field is

{U_B}

. Then

View answer and explanation

Correct option: A

{U_E} = {U_B}

Option A (

{U_E} = {U_B}

) is correct because in free space, the energy of an electromagnetic wave is equally distributed between the electric and magnetic fields.
