Definition: The word "infrared" is used to describe a type of electromagnetic radiation (or light) that has longer wavelengths than visible light but shorter wavelengths than radio waves. You can't see infrared light with your eyes, but it can be felt as heat.
In more advanced contexts, "infrared" can refer to technologies or applications, such as: - Infrared thermography: A technique that uses infrared cameras to detect temperature differences in objects, useful in building inspections or medical diagnosis. - Infrared spectroscopy: A method that studies materials by analyzing how they absorb infrared light, important in chemistry and materials science.
While "infrared" primarily refers to the specific type of electromagnetic radiation, it generally denotes anything that relates to or uses this type of light.
There are no specific idioms or phrasal verbs associated with "infrared," but you might encounter phrases like "infrared technology" or "infrared sensors" in technical discussions.
"Infrarred" is an important term in science and technology, especially related to heat and energy.
