In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.

In the aerospace context, wavelength refers to the distance between two consecutive peaks or troughs of a wave, such as a sound wave, an electromagnetic wave, or a gravitational wave. Wavelength is an important concept in the field of electromagnetism and it is commonly used to describe the properties of electromagnetic radiation such as light, radio waves, and X-rays.

Examples of wavelength in the aerospace context include:

  • Wavelengths of radio waves, which are used for communication with spacecraft and the tracking of aircraft.

  • Wavelengths of infrared radiation, which are used for sensing temperature and for imaging in various aerospace applications such as remote sensing and thermal imaging.

  • Wavelengths of visible light, which are used for navigation, imaging, and communication on aircraft and spacecraft.

  • Wavelengths of ultraviolet radiation, which are used for sensing the composition of planetary atmospheres and for imaging the surface of celestial bodies.

  • Wavelengths of X-rays, which are used for imaging and sensing in aerospace applications such as space observation, radiation monitoring, and in situ material analysis.

  • Wavelengths of gamma rays, which are used for sensing the high energy phenomena in space such as supernovae, gamma-ray bursts, and black holes.

In aerospace, wavelength plays an important role in the design and operation of sensors, cameras, communications systems, and other equipment that rely on electromagnetic radiation. Understanding the properties of different wavelengths and how they interact with materials is essential for the design and operation of aerospace systems, such as antennas, cameras, and sensors.
