Question
A neodymium-glass laser emits short pulses of high-intensityelectromagnetic waves. The electric field of such a wave has an rmsvalue of Erms=2.0E9 N/C. Find the average power of each pulse thatpasses through a 1.6E-5 m2 surface that is perpendicularto the laser beam. Please Help A neodymium-glass laser emits short pulses of high-intensityelectromagnetic waves. The electric field of such a wave has an rmsvalue of Erms=2.0E9 N/C. Find the average power of each pulse thatpasses through a 1.6E-5 m2 surface that is perpendicularto the laser beam. Please HelpExplanation / Answer
Rms electric field E = 2*10^9 N / C
Area A= 1.6 * 10 ^ -5 m^ 2
