Need help answering Parts A, B, and C for the question below:

In an EM wave traveling west, the B field oscillates up and down vertically and has a frequency of 94.0 kHz and an rms strength of 7.2510^9 T. Assume that the wave travels in free space.

Part A: What is the frequency of the electric field?

Part B: What is the rms strength of the electric field? Part C: What is the direction of its oscillation?

Choose an answer below:

A. The electric field oscillates vertically.

B. The electric field oscillates along the horizontal north-south line.

C. The electric field oscillates along the horizontal west-east line.

D. None of the above.
