Question

In an electromagnetic wave, the amplitude of electric field is 1V/m. The frequency of wave is $5 cross times 10 to the power of 14 end exponent$ Hz The wave is propagating along z-axis. The average energy density of electric field, in Joule /m³, will be

$1.1 \times 10^{- 11}$
$2.2 \times 10^{- 12}$
$3.3 \times 10^{- 13}$
$4.4 \times 10^{- 14}$

The correct answer is: $2.2 cross times 10 to the power of negative 12 end exponent$
