An EM wave radiates outwards from a dipole antenna, with 
as the amplitude of its electric field vector. The electric field 
which transports significant energy from the source falls off as
A
B
C
D
remains constant
Text Solution
Verified by ExpertsThe correct answer is:
C
From a dipole antenna, the electromagnetic waves are radiated outwards.
The amplitude of electric field vector 
which transports significant energy from the source falls off inversely as the distance r from the antenna, i.e. 
.
