A 25 m long antenna is mounted on an antenna tower. The height of the antenna tower is 75 m.
Question:

A 25 m long antenna is mounted on an antenna tower. The height of the antenna tower is 75 m. The wavelength (in meter) of the signal transmitted by this antenna would be :

  1. 300

  2. 400

  3. 200

  4. 100


Correct Option: 4,

Solution:

Length of Antena $=25 \mathrm{~m}=\frac{\lambda}{4}$

$\Rightarrow \lambda=100 \mathrm{~m}$
