Find the characteristic impedance of a quarter wave with input and loa

1.	Find the characteristic impedance of a quarter wave with input and load impedances given by 50 and 25 respectively.(a) 50(b) 25(c) 75(d) 35.35I have been asked this question in my homework.Asked question is from Transmission Line Equations topic in section Transmission Lines of Electromagnetic Theory
Answer» Right answer is (d) 35.35 To explain I would say: For a quarter line wave, the CHARACTERISTIC impedance is the geometric mean of input and load impedances. Thus Zo^2 = Zin ZL. On substituting for Zin = 50 and ZL = 25, we get Zo^2 = 50 X 25. The characteristic impedance will be 35.35 OHM.
