100m long antenna is mounted on a 500m tall building. The complex can become a transmission tower for waves with λ

(a) ~ 400 m

(b) ~ 25 m

(c) ~ 150 m

(d) ~ 2400 m

Answers (1)

It can easily be calculated as

Length of the building = 500\: m (l)

Length of the antenna = 100\: m (L)

And thus the wavelength of the wave transmitted would be= 4L= 4(100) = 400 \: m
