An EM wave radiates outwards from a dipole antenna, with E0 as the amplitude of its electric field vector. The electric field E0 which transports significant energy from the source falls off as a) 1/r3 b) 1/r2 c) 1/r d) remains constant
Correct option is C) A diode antenna radiates the electromagnetic wave outwards. The amplitude of electric field vector (E0) which transports significant energy from the source falls intensity inversely as the distance (r) from the antenna, i.e,E0∝r1
