A lossless transmission line with air dielectric is 6 m long. What is the line length at 30 MHz?-A-1 wavelength longB-0.5 wavelength longC-0.6 wavelength longD-0.25 wavelength long-C-0.6 wavelength long

C 0.6 wavelength long V = 3 x 108 m/s for lossless line ∴ ∴ Line length = = 0.6 wave length long.
