säteilylämpöön
Säteilylämpöön refers to heat transfer through electromagnetic radiation. Unlike conduction and convection, which require a medium to transfer heat, radiation can travel through a vacuum. The primary source of radiation heat transfer for Earth is the Sun. All objects with a temperature above absolute zero emit thermal radiation. The intensity and spectrum of this radiation depend on the object's temperature. Hotter objects emit more radiation and at shorter wavelengths.
When this radiation strikes another object, it can be absorbed, reflected, or transmitted. The absorbed radiation
Examples of säteilylämpöön in everyday life include feeling the warmth of a fire without being directly in
