The wavelength of a wave with a frequency of 6 GHz in air is(a) 50(b) 5(c) 0.5(d) 0.05I had been asked this question by my college professor while I was bunking the class.My enquiry is from Transmission Line Secondary Parameters topic in division Transmission Lines of Electromagnetic Theory

Answer»

Correct OPTION is (d) 0.05

For explanation: The wavelength is given by the ratio of the velocity to the frequency of the WAVE. In air medium, the velocity can be assumed as the speed of light. On SUBSTITUTING for v and F, we get λ = v/f = 3×10^8/6×10^9 = 0.05 units.
