It makes things that are hot look like they are glowing. In infrared light, hot things look bright yellow and orange. Items that are colder, such as an ice cube, are purple or blue.
WebThis explains why as an object gets hotter and hotter, it goes from invisible, to red, to blue, and finally to white-hot, which corresponds to the decreasing wavelengths of this higher energy light. See blackbody radiation for more details on how temperature relates to objects and their radiant heat. Visible vs Infrared WebNov 17, 2024 · Nearly all thermal energy on Earth originates from the sun and radiates to the surface of our planet, traveling in the form of electromagnetic waves, such as visible light. Materials on Earth then absorb these waves to be used for energy or reflect them back into space. In an energy transformation, energy changes form.
