Vedclass · Answer

(B) The efficiency of an antenna in radiating electromagnetic waves depends on its size relative to the wavelength of the signal. For effective transmission,the antenna length $L$ should be comparable to the wavelength $\lambda$ of the signal (e.g.,$L = \lambda/4$). Since $\lambda = c/f$,where $c$ is the speed of light and $f$ is the frequency,a higher frequency $f$ results in a smaller wavelength $\lambda$. Smaller wavelengths allow for smaller,more practical antenna sizes. Therefore,high-frequency waves can be transmitted more efficiently.
