The chemical effect of light – causes chemical reactions: photosynthesis, photography (the formation of silver when light falls on silver bromide crystals), vision (decomposition of molecules in the retina).
Electric action is the ripping out of electrons from the substance, as well as the transformation of bound electrons into free ones (the appearance of an electric current): digital cameras and video cameras, photo effect, solar batteries, light sensors.
Thermal effect – when radiation is absorbed, the radiation energy is converted into internal energy (body heating). Ice under the influence of sunlight turns into water, and water – into steam. Heating the surface of the Earth by sunlight leads to fires, hurricanes, etc.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
