Sentences with phrase «emissions wavelengths»
"Emissions wavelengths" refers to the specific range or type of light waves that are released or emitted by a source such as a light bulb, a star, or even certain gases. It represents the specific colors or frequencies that are emitted, which can help scientists identify and study different objects or phenomena in the universe. Full definition
