Answer:
Poynting vector, [tex]S=1.03\times 10^{7}\ W/m^2[/tex]
Explanation:
It is given that, The electric and magnetic fields of an electromagnetic wave are given by :
Electric field, [tex]E=6.25\times 10^{-3}\ V/m[/tex]
Magnetic field, [tex]B=2.08\times 10^{-11}\ T[/tex]
We need to find the Poynting vector for this wave. the Poynting vector is given by :
[tex]S=\dfrac{1}{\mu_o}EB[/tex]
[tex]S=\dfrac{1}{4\pi \times 10^{-7}}\times 6.25\times 10^{-3}\times 2.08\times 10^{-11}[/tex]
[tex]S=1.03\times 10^{7}\ W/m^2[/tex]
So, the Poynting vector for this wave is [tex]1.03\times 10^{7}\ W/m^2[/tex]. Hence, this is the required solution.
