How does light energy get changed to heat energy?

Postby NeedsAPbiohelp » Tue Sep 06, 2011 2:13 am

How exactly does light transform into heat--for instance, when sunlight warms up a brick wall? I understand that electrons in the atoms in the wall absorb the light, but how does that absorbed sunlight turn into thermal energy? How does light get transformed into vibrational energy?

energy can freely change into another kinds of energy

Cis or trans? That's what matters.
