Sentences with phrase «extreme ultraviolet»
"Extreme ultraviolet" refers to a type of light that has a very short wavelength and carries a lot of energy. It is a form of electromagnetic radiation that cannot be seen by our eyes but can be used in technologies like cutting-edge microchips and space telescopes to capture high-resolution images. Full definition
