A quantum of light coming from the deeper layers of the star is captured by an atom of its atmosphere. What is the further “fate” of the atom?
Three situations are possible: a) a quantum of light can be re-emitted at the same frequency, but in a different direction, which leads to weakening of the radiation; b) a quantum can be re-emitted at a different frequency, which leads to a redistribution of the intensity over the spectrum; c) the energy of a quantum can be used to increase the kinetic energy of the atom, while the internal energy of the substance increases.
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.
