MHz (Megahertz)

MHz (Megahertz) is a unit of frequency measurement that represents one million cycles per second. In the context of space and astronautical engineering, MHz is commonly used to measure the frequency of electromagnetic waves, such as radio waves, microwaves, and infrared radiation, which are used for communication, navigation, and remote sensing. The frequency of these waves is important because it determines their wavelength, which affects their ability to penetrate different materials and propagate through space. For example, radio waves with a frequency of several MHz can penetrate the Earth's atmosphere and be used for long-distance communication with spacecraft, while higher frequency waves, such as X-rays and gamma rays, are absorbed by the atmosphere and require specialized instruments to detect them.
