A) \[\frac{1}{{{r}^{3}}}\]
B) \[\frac{1}{{{r}^{2}}}\]
C) \[\frac{1}{r}\]
D) remains constant
Correct Answer: C
Solution :
Option [c] is correct |
Explanation: A diode antenna radiates the electromagnetic waves outwards. The amplitude of electric field vector \[({{E}_{0}})\] which transports significant energy from the source falls inversely as the distance \[(r)\] from the antenna. As we know that electromagnetic waves are radiated from dipole antenna and radiated energy, so\[\operatorname{E}\propto \frac{1}{r}\]. |
