9) Answer: (E) A and B
The E and B fields are perpendicular to each other and to the direction of propagation. Thus option A is true.
We have, E = vB
=> E/B = v
Thus, option B is also true.

Were Maxwell's efforts more important than the individual discoveries of Gauss, Ampère, and Faraday? Explain your answer. Options: A)Yes, because Maxwell's addition, modification, and insights resulted in the identification of light as an electromagnetic wave. B)No, because Ampère's law and Faraday's law together already had the necessary elements to describe electromagnetic waves. C)Yes, because before Maxwell's efforts, Gauss's, Ampère's, and Faraday's laws treated electric and magnetic fields as completely independent. D)No, because Gauss's law for magnetism has since been shown...
