What is an everyday example showing how heat is absorbed from visible radiation and transferred to infrared radiation?
Infrared Radiation is at a Frequency that is outside of the range of the Visible Spectrum. Visible light does not 'become' Infrared Light. If a light source is giving off energy in the form of HEAT it is emitting Infrared Energy, as well as Visible Light. A light source can also "Heat" matter by giving off energy such as X-Rays, or Gamma Rays, or more commonly MICROWAVE Radiation.
