What does "emitted" mean?

"Emitted" means to give off or release, and this definition can be understood through its use in various contexts, such as physics, biology, and everyday situations. When something is emitted, it refers to the act of sending out energy, light, sound, or substances. For example, a light bulb emits light, and a factory may emit smoke or pollutants into the air. The word is often used to describe processes where one substance or form of energy is sent out or released into the environment.

The other options do not capture the essence of the term "emitted." Absorbing would imply taking something in rather than releasing it, containing means to hold within something else rather than allowing it to escape, and hiding involves concealing rather than releasing. These distinctions highlight why "to give off or release" is the most accurate meaning of "emitted."
