Question

How much energy is transported across a

Answer 1

Explanation:

Let us assume that Z is the energy transported across an area of $1.00 cm^{2}$ per hour by an electromagnetic wave with an r.m.s speed of 21.5 V/m.

Therefore, first we will calculate the current as follows.

                  I = $\frac{E_{rms^{2}}}{c \times \mu_{o}}$

                    = $\frac{10^{-4} \times 3600 \times (21.5)^{2}}{3 \times 10^{8} \times 4 \times 3.14 \times 10^{-7}}$

                    = 0.441 J

Therefore, we can conclude that 0.441 J energy is transported across a given EM wave.
