The due time is Central time. 001 (part 1 of 2) 1 points The magnetic field amplitude of an electro- magnetic wave is 4 × 10 - 6 T. The speed of light is 2 . 99792 × 10 8 m / s . Calculate the amplitude of the electric field if the wave is traveling in free space. Correct answer: 1199 . 17 N / C. Explanation: Let : c = 2 . 99792 × 10 8 m / s and B = 4 × 10 - 6 T . According to Maxwell’s equations for an electromagnetic wave in vacuum the relation between the amplitude of the magnetic field and the amplitude of the electric field must be E = c B = (2 . 99792 × 10 8 m / s) (4 × 10 - 6 T) = 1199 . 17 N / C . The same relation applies even when the ve- locity of light in the medium is not c , in general, E = v B where v is the velocity of light in that medium. 002 (part 2 of 2) 1 points Calculate the amplitude of the electric field

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
