1.	The reflection coefficient of a wave travelling through two media having magnetic intrinsic impedances of 2 and 1 respectively is(a) ^1⁄2(b) ^1⁄3(c) ^1⁄4(d) ^1⁄5This question was addressed to me in a national level competition.My enquiry is from Intrinsic Impedance and Propagation Constant in division Transmission Lines of Electromagnetic Theory
Answer» The correct choice is (b) ^1⁄3 Explanation: The reflection coefficient in terms for MAGNETIC INTRINSIC impedance is R = η1 – η2/η1 + η2. On SUBSTITUTING the given data, we GET R = 2 – 1/2 + 1 = 1/3.
