The intensity of the incident light is very similar to that transmitted and that explains why they are usually not so prone to heat up. The transparent bodies they are those that let through almost all the light that falls on them. The aluminumFor example, it is opaque in the frequency range of visible light, but is completely transparent in the frequency of ultraviolet rays. On the other hand, the transparency condition and opacity depends in most cases on the energy (or frequency) of the light that falls on an object. The object behavior with respect to photons it is not binomial and sometimes phenomena such as reflection of light (the change of direction that occurred at the separation surface) or refraction (the change in speed when passing from one material medium to another) can occur.
On the contrary, when it comes to transparent objects, the leap they have to make to be absorbed is not possible and the photons go through the object in search of new electrons to excite. The transfer of energy is what explains why objects do not let light pass through, but they heat up the more intense this energy is: in this sense, dark objects are more likely to absorb photons than light ones. The difference, precisely, lies in the moment in which the photons try to pass the energy: opaque objects succeed and, therefore, the photons are “consumed”.
