A 50m long antenna is mounted on a 200 m tall building. The complex can become transmission tower for waves with wave length
Answer & explanation
Correct answer: option 2
The correct answer is option (2) : $∼200 m$
According to ques, length of building is = 200 m
And length of antenna is = 50 m
Wavelength of the wave that can be transmitted is as follows:
$λ = 4l$
$⇒ λ = 4 × 50 = 200 m$
