Hi, I am new to this forum so I dont really know if this question already exists..(adsbygoogle = window.adsbygoogle || []).push({});

My question is: When an electron absorbs a foton and climbs to the next energy gap and then returns again, as the energy is quantum energy, how is possible that the foton reemited by the electron has the same energy as the original foton, without any energy lost as the classical thermodinamics would suggest? Is there any energy lost during this transformation?

Thanks!!
