h: height of antenna λ: wavelength of signal h <λ λ> h λ>400 m

Q. An antenna is mounted on a $400 m$ tall building. What will be the wavelength of signal of signal that can be radiated effectively by the transmission tower upto a range of $44 km$ ?

37.8 m

605 m

75.6 m

302 m

$h$ : height of antenna
$λ$ : wavelength of signal
$h < λ$
$λ > h$
$λ > 400 m$
