Question
Energy density of an electromagnetic wave of intensity $0.02 \mathrm{Wm}^{-2}$ is(A) $6.67 \times 10^{-11} \mathrm{Jm}^{-3}$(B) $6 \times 10^{6} \mathrm{Jm}^{-3}$(C) $1.5 \times 10^{10} \mathrm{Jm}^{-3}$(D) none of the above
Step 1
Step 1: The energy density (u) of an electromagnetic wave is given by the formula: \[ u = \frac{I}{c} \] where I is the intensity of the wave and c is the speed of light. Show more…
