What is Blackbody Radiation: Explained in Simple Terms

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical because no object can be a perfect absorber of electromagnetic radiation. Think of it this way: when you heat an iron rod, it becomes extremely hot, and its color changes to dull red, followed by bright red, orange and then yellow. This is a good example of how black body radiation works. In this video, you will learn about blackbody radiation, the blackbody radiation curve and how it helps to understand electromagnetic radiation and celestial bodies.
