How does light energy turn into heat energy?

I understand that electrons in the atoms in the wall absorb the light, but how does that absorbed sunlight turn into thermal energy? ... such as water or a brick primarily because the long wavelength, or infrared, portion of the sun's radiation resonates well with molecules in the material, thereby setting them into motion. read more

"Heat" (not heat energy) is defined as the transfer of energy between two systems as a result of a temperature difference only. Consequently light emitted by a hot object and absorbed by a cooler object is transferring energy from one to another as a result of the temperature difference. read more

Light does not turn into heat, it heats up another system. Light behaves as both particles and waves. The particles are called photons and they possess momentum. When these particles strike another object, the momentum is transferred as kinetic energy to the other particles, thus heating up the system. read more
