Question

In an electromagnetic wave, the electric and
magnetic fields are 100 V m⁻¹ and 0.265 A m⁻¹.
The maximum energy flow is
(a) 26.5 W/m² (b) 36.5 W/m²
(c) 46.7 W/m² (d) 765 W/m²

Answer 1

Answer:

your option a) 26.5 W/m^2 is correct.

Explanation:-

Here,amplitude of electric field, Eo=100V/m; amplitude of magnetic field,

Ho= 0.265 A/m.

We know that the maximum ate energy flow,

S=Eo×Ho=100×0.265=26.5W/m^2.
