What does frequency refer to in the context of electromagnetic waves?

Frequency, in the context of electromagnetic waves, is defined as the number of cycles that pass a given point in one second. It is a fundamental property of all types of waves, including light waves. The unit of frequency is the hertz (Hz), where one hertz corresponds to one cycle per second. High-frequency waves have more cycles passing a point in the same time frame compared to low-frequency waves. This characteristic is essential in distinguishing different types of electromagnetic radiation, such as radio waves, visible light, and X-rays, each of which operates at different frequency ranges. The other options relate to different concepts: the first option discusses wavelengths but does not define frequency; the third option pertains to the spectrum of emitted light rather than cycles; and the fourth option concerns the speed of light, which, while related to wave properties, does not define frequency itself.
