Hertz (Hz)
Hertz (Hz) is the unit of frequency measurement in the International System of Units (SI). It is defined as one cycle per second. In space and astronautical engineering, Hertz is commonly used to measure the frequency of electromagnetic waves, including radio waves, microwaves, and light. The frequency of these waves is important in determining their properties and behavior, such as their wavelength, energy, and propagation characteristics. For example, the frequency of a radio wave determines the channel on which it can be transmitted and received, while the frequency of a laser beam determines its color and ability to penetrate materials.
