A signal is to be transmitted through a wave of wavelength $$\lambda$$, using a linear antenna. The length $$l$$ of the antenna and effective power radiated $$P_{\text{eff}}$$ will be given, respectively, as- ($$K$$ is a constant of proportionality)

A

$$\frac{\lambda}{8}$$, $$P_{\text{eff}} = K\left(\frac{l}{\lambda}\right)$$

B

$$\frac{\lambda}{16}$$, $$P_{\text{eff}} = K\left(\frac{l}{\lambda}\right)^3$$

C

$$\frac{\lambda}{5}$$, $$P_{\text{eff}} = K\left(\frac{l}{\lambda}\right)^{\frac{1}{2}}$$

D

$$\lambda$$, $$P_{\text{eff}} = K\left(\frac{l}{\lambda}\right)^2$$
