The velocity of the transmission line with a frequency of 35 radian/s

1.	The velocity of the transmission line with a frequency of 35 radian/s and phase constant of 68.5 is(a) 1.95(b) 2.36(c) 4.56(d) 3.48This question was posed to me by my school principal while I was bunking the class.I would like to ask this question from Lossless and Distortionless Line in chapter Transmission Lines of Electromagnetic Theory
Answer» RIGHT answer is (a) 1.95 To EXPLAIN I would say: The VELOCITY of the wave in a transmission line is the ratio of the frequency to the phase constant. THUS V = ω/β. On substituting for ω = 35 and β = 68.5, we get v = 68.5/35 = 1.95 units.
