WebThe amount of heat produced by light incident upon an object depends on the material properties. Some wavelengths will be reflected, some absorbed, and some transmitted. As you point out, the associated energy of the photon is important in determining what sort of interaction will take place. WebIf the photon energy is absorbed, the energy from the photon typically manifests itself as heating the matter up. The absorption of light makes an object dark or opaque to the …
