What is represented by one megahertz (MHz) in terms of cycles per second?

One megahertz (MHz) is defined as one million cycles per second. The prefix "mega-" in the metric system denotes a factor of one million (10^6). Thus, when discussing frequencies measured in hertz (Hz), one megahertz indicates that something occurs one million times in one second.

This concept is crucial in fields such as telecommunications and electronics, where the frequency of signals often plays a significant role in performance and capabilities. For example, radio frequencies are typically expressed in megahertz to indicate the number of cycles per second of the radio waves. Understanding this measurement allows one to grasp how data is transmitted and processed in various technological applications.

The other choices do not correctly represent the value of one megahertz, as they signify different orders of magnitude in terms of cycles per second.
