Ch. 22 # 6
How much energy is transported across a 1.45 cm2 area per hour by an EM wave whose E field has an rms strength of 37.3 mV/m ? The wave travels in free space. Express your answer using three significant figures.
Homework Answers
Concept - find the amplitude of magnetic field using the RMS value. Use the amplitude to find the intensity and use the intensity to find the power crossing the area. Use the relation between energy and power to find the energy per hour
