Hi, I have a few questions about Stefan-Boltzmann's law. Let's say that the temerature of an object increases for 2 degrees Celsius, that means that the emmited energy of a surface of that object will increase 16 times. Is this happening because the number of photons is increased 16 times or is the energy of 1 photon increased 16 times or something in between? What is the correlation between temperature of an object and the number of photons it emmits (if one exists)? Let's say in the example of light bulb, if the temerature of a light bulb increases will the light bulb glow brighter, and if it does is it because of an increase of a number of photons or the increase of the energy of 1 photon?
