  Not meaning to be the achkshually guy, but, heat is a kind of "light" (EM radiation) within the Infrared range of the spectrum. We can't see it, but snakes can.

    If I may achkshually your achkshually, I believe that heat is the energy in the collective motion of particles of matter, and infrared photons are one way that energy can be radiated away from one body and absorbed by another.

    I will uno reverse umm achkshually you. Heat is not synonymous with infrared light. Objects with heat will emit energy into their environment as EM radiation. That heat can also be conducted away through contact with another object.

    All objects with heat do give off a wide spectrum of EM radiation, with the uppermost frequency being proportional to the object’s temperature. A very cold object might only give off radio waves. Room temperature objects, like you, glow in the infrared. Above 500C or so, objects start glowing visibly red, then orange and yellow. A phenomenon we call incandescence.

    Objects that absorb light can and often do increase in heat, PV panels turn some of the energy that strikes them as light into electrical energy rather than thermal energy.
