The standing wave ratio of the wave with maximum and minimum electric

1.	The standing wave ratio of the wave with maximum and minimum electric field intensities of 12 and 4 is(a) 12(b) 4(c) 3(d) 48I have been asked this question in an interview for internship.Origin of the question is Intrinsic Impedance and Propagation Constant in section Transmission Lines of Electromagnetic Theory
Answer» Right choice is (C) 3 Explanation: The SWR is DEFINED as the RATIO of maximum electric FIELD intensities to the minimum field intensities. It is given by S = EMAX/EMIN. Thus for the given data, S = 12/4 = 3.
