Given below are two statements
Statement I: For transmitting a signal, size of antenna ($$l$$) should be comparable to wavelength of signal (at least $$l = \dfrac{\lambda}{4}$$ in dimension).
Statement II: In amplitude modulation, amplitude of carrier wave remains constant (unchanged).
In the light of the above statements, choose the most appropriate answer from the options given below

Statement I: For effective transmission of a signal, the size of the antenna should be comparable to the wavelength of the signal (at least $$l = \frac{\lambda}{4}$$). This is correct.

Statement II: In amplitude modulation (AM), the amplitude of the carrier wave is modulated (varied) according to the information signal. The amplitude does NOT remain constant. This statement is incorrect.

Therefore, Statement I is correct but Statement II is incorrect.
