(a) ~ 400 m

(b) ~ 25 m

(c) ~ 150 m

(d) ~ 2400 m

Answer:

The correct option is (a) ~ 400 m

Explanation:

According to the question, the length of building ois

l = 500m

and Length of antenna is 100m

The wavelength of the wave that can be transmitted by the antennae is as follows:

λ = 4l

λ = 4×100

λ = 400m
