Vedclass · Answer

(D) For an antenna to be effective,its length $L$ should be a fraction of the wavelength $\lambda$ of the signal it transmits. Typically,the minimum length of an antenna is given by $L = \frac{\lambda}{4}$. Given the length of the antenna $L = 25\, m$. Substituting the value into the formula: $25 = \frac{\lambda}{4}$. Solving for $\lambda$: $\lambda = 25 	imes 4 = 100\, m$. Thus,the wavelength of the signal is $100\, m$.

$A$ $25\, m$ 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
