E = (50 N/s) sin (t – x/c)

Energy 5.5 × 10^-12 J., vol v =?

$u = \frac{1}{2} ε_{0} E^{2} \to$ energy density

$? u = \frac{U}{v} \Rightarrow U = u v$

= $\frac{1}{2} ε_{0} E^{2} . v$

$v = \frac{5.5 \times 1 0^{- 12} \times 2}{8.55 \times 2500 \times 1 0^{- 12}} \times 1 0^{6} c m^{3}$

= 497

$≅ 500 c m^{3}$
