Multiple choice

A transmission line of characteristic impedance 50 Ω is terminated by a 50 Ωload. When excited by a sinusoidal voltage source at 10 GHz, the phase difference between two points spaced 2 mm apart on the line is found to be $\frac{2 \pi}{\lambda}$ radians. The phase velocity of the wave along the line is

  1. 3 x 108 m/s

  2. 0.8 x 108 m/s

  3. 1.2 x 108 m/s

  4. 1.6 x 108 m/s
