C.the frequency of the wave.***
D.the loudness of the wave.

Correct

thanks

No problem.

C.the frequency of the wave.

So whats right?

It's C.

To determine the correct answer, let's go through the options:

A. The speed of the wave: The speed of a wave refers to how quickly it travels from one point to another. However, FM signals do not travel as changes in the speed of the wave, so this option is not correct.

B. The amplitude of the wave: The amplitude of a wave refers to the height or intensity of the wave. While the amplitude of an FM signal can change, it does not primarily travel as changes in amplitude, so this option is not correct.

C. The frequency of the wave: The frequency of a wave refers to the number of complete cycles it completes in a given time period. FM signals, or Frequency Modulation signals, primarily travel as changes in frequency. As the name suggests, FM signals modulate or change the frequency of the wave to carry information, so this is the correct option.

D. The loudness of the wave: The loudness of a wave refers to the intensity or volume of the sound it produces. While the loudness can be considered in the context of FM signals, the primary mode of transmission for FM signals is changes in frequency, not loudness, so this option is not correct.

Therefore, the correct answer is C. The frequency of the wave.
