Question:
A $25 \mathrm{~m}$ long antenna is mounted on an antenna tower. The height of the antenna tower is $75 \mathrm{~m}$. The wavelength (in meter) of the signal transmitted by this antenna would be :
Correct Option: , 4
Solution:
(4)
Length of Antena $=25 \mathrm{~m}=\frac{\lambda}{4}$
$\Rightarrow \lambda=100 \mathrm{~m}$
