What should be the length of the dipole antenna for a carrier wave of frequency \[\mathbf{3}\text{ }\times \text{ }\mathbf{1}{{\mathbf{0}}^{\mathbf{8}}}\] Hz?                    

Answer:

                Length of a dipole antenna \[=\frac{\lambda }{2}=\frac{c}{2v}=\frac{3\times {{10}^{8}}}{2\times 3\times {{10}^{8}}}=\text{0}\text{.5m}\]
