At one instant, the electric and magnetic fields at one point of an electromagnetic wave are E
Question:
At one instant, the electric and magnetic fields at one point of an electromagnetic wave are E = (200î + 300ĵ - 50k̂) V/m and B = B0(7.3î - 7.3 ĵ + ak̂) μT.
a. What are the values of a and B0?
b. What is the Poynting vector at this time and position?
