1.	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 GHzI 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
Answer» Right OPTION is (B) 0.133 GHz Explanation: The frequency and wavelength relation is given by F = V/λ. On SUBSTITUTING for v and λ, we get f = 4 x 10^8/3 = 0.133 GHz.
