Hello, why do every atom with a temperature different from the absolute 0 emittes infrared radiation? Where does it came from?
Thank you!
Thank you!
scientifico said:So infrared radiation is just energy, part of the atomic energy?

So a single atom will have no emission of any kind?kurros said:So first, an individual atom does not have a temperature, only a collection of them does.

scientifico said:If I take for example 1 g of Fe and I heat it up to 500 °C, then I take 0.1 g Fe at the same temperature will they have the same emission?
Infrared radiation is a type of electromagnetic radiation that has a longer wavelength than visible light. It is commonly referred to as "heat radiation" because it is often felt as heat.
Infrared radiation comes from a variety of sources, including the sun, human-made objects such as heaters and electronic devices, and even our own bodies. It is also emitted by objects that are at room temperature or warmer, as all objects with a temperature above absolute zero emit some form of infrared radiation.
Infrared radiation has a longer wavelength than visible light, making it invisible to the human eye. It also has less energy than visible light and can pass through certain materials, such as glass and plastic, that block other forms of radiation. Infrared radiation is also responsible for the feeling of warmth from the sun, whereas ultraviolet radiation from the sun can be harmful to our skin.
Infrared radiation is generally not considered harmful to humans in small doses. However, prolonged exposure to high levels of infrared radiation can lead to skin burns and eye damage. It is important to protect yourself from excessive exposure to infrared radiation, especially in industrial or occupational settings.
Infrared radiation has a wide range of applications in everyday life. Some common uses include thermal imaging cameras for detecting heat signatures, remote controls for electronic devices, and infrared saunas for relaxation and health benefits. It is also used in industrial processes, such as drying and heating materials, and in medical imaging techniques such as infrared spectroscopy.
