🤓 Based on our data, we think this question is relevant for Professor Ford's class at TAMU.
Sinusoidal electromagnetic waves from a radio station process pass perpendicularly through an open window that has area 0.400 m2. The intensity of the wave is constant over the area of the window. The wave carries 0.800 J of energy through the window in 5.00 s. (Note: ε0 = 8.854 x 10-12 C2/N•m2 and μ0 = 4π x 10-7 T•m/A) At the window, what is the amplitude of the magnetic field of the wave?
