The frequency of a wave travelling in a transmission line with velocity 4 x 108 and wavelength 3 units is
(a) 0.75 GHz
(b) 0.133 GHz
(c) 7.5 GHz
(d) 1.33 GHz
I have been asked this question in a national level competition.
The doubt is from Transmission Line Secondary Parameters in division Transmission Lines of Electromagnetic Theory
