Chapter 5, Problem 5.35P

For a lossless open-circuited line, express the sending-end voltage, $V_1,$ in terms of the receiving-end voltage, $V_2,$ for the three cases of short-line model, medium-length line model, and long-line model. Is it true that the voltage at the open receiving end of a long line is higher than that at the sending end, for small $\beta 1?$
