An `EM` wave radiates out wards from a dipole antenna with `E_(0)` as the amplitude of its electric filed vector. The electric field `E_(0)` which transports significant energy from the source falls off asA. `1/(r^(3))`B. `(1)/(r^(2))`C. `(1)/(r)`D. remain constant |

Answer» Correct Answer - C From a dipole antenna, the electromagnetic waves are radiated outwards. The amplitude of electric field vector `(E_(0))` which transports singnificant energy from the source falls off inversely as the distance `(r)` from the antenna ie., `E_(0)prop (1)/(r)` |
