Question 85 of 165

For an electromagnetic wave travelling in free space, the relation between average energy densities due to electric (Ue)\left({U}_{e}\right) and magnetic (Um)\left({U}_{m}\right) fields is :

Show answer and solution

Answer: (A) Ue=Um{U}_{e}={U}_{m}

In EMWEMW, Average energy density due to electric (Ue)\left({U}_{e}\right) and magnetic (Um)\left({U}_{m}\right) fields is same.
