What characteristic of high frequency carrier waves allows them to carry more information?

High frequency carrier waves are able to carry more information primarily due to their increased ability to accommodate a higher number of cycles per second, which allows for a greater amount of data encoding in a given time frame. When carrier waves are closer together in frequency, this means that more distinct signal variations can occur within a given bandwidth.

This characteristic enables frequency modulation techniques to involve more complex and varied signal alterations, leading to enhanced data transmission capacity. As a result, high frequency waves can effectively transmit more bits of information over the same duration compared to lower frequency waves, which have wider spacing and typically lower data capacity.

In contrast, longer wavelengths and higher amplitudes do not directly correlate with increased information capacity, and lower frequency waves do not support the same data density as higher frequency waves. Thus, the proximity of the carrier waves is a crucial attribute in allowing high frequency waves to transport more information.
