Activity 3: Making thermal radiation visible
All bodies emit heat radiation (or thermal radiation) - however, this is only visible to the human eye at higher temperatures. The thermal radiation of the human body, like the thermal radiation of the earth, is invisible to us - it lies in the infrared range and can only be made visible with a thermal imaging camera.
In its properties, thermal radiation also differs from visible light: while thermal radiation is intercepted by glass and greenhouse gases, for example, visible light passes through these materials unhindered.
