1.	The standing wave ratio of a wave travelling through two media having intrinsic impedances of 3 and 2 is(a) ^2⁄3(b) ^3⁄2(c) ^1⁄5(d) 5I have been asked this question during an online exam.Query is from Intrinsic Impedance and Propagation Constant topic in section Transmission Lines of Electromagnetic Theory
Answer» The correct OPTION is (B) ^3⁄2 Best explanation: The standing wave ratio is given by the ratio of the intrinsic impedance of medium 1 to the intrinsic impedance of medium 2. THUS S = η1/η2. On substituting for η1 = 3 and η2 = 2, we GET S = 3/2.
