38Å

38Å is a designation that refers to a specific wavelength of light, approximately 38 angstroms. The angstrom (Å) is a unit of length equal to 10⁻¹⁰ meters, commonly used for atomic and molecular dimensions, as well as for wavelengths of electromagnetic radiation. A wavelength of 38 angstroms falls within the extreme ultraviolet (EUV) or soft X-ray portion of the electromagnetic spectrum. This region of the spectrum is characterized by high energy photons, capable of interacting with matter in ways that visible light cannot. For instance, radiation at this wavelength can ionize atoms and molecules, and is strongly absorbed by most materials, including air. Consequently, experiments involving 38Å radiation are typically conducted in a vacuum or controlled atmosphere. Applications for light in this wavelength range include certain types of spectroscopy, lithography for semiconductor manufacturing, and potentially in scientific research for studying the properties of materials at a very fine scale. The specific source and generation method for 38Å radiation would depend on the intended application.
