If both the length of an antenna and the wavelength of the signal to be transmitted are doubled, the power radiated by the antenna

A

is doubled

B

is halved

C

remains constant

D

is quadrupled

Text Solution

Verified by Experts

The correct Answer is:
C
Power radiatated by the antenna is proportional to `((1)/(lambda))^(2)` when both the length of the antenna 1 and wavelength of the signal `lambda` are doubled, the power radiated by the antenna remains constant.
