The concept of modes in optics and photonics
... The energy throughput of an optical system is limited by the number of accepted modes and the number of photons per mode. Since the number of photons per mode cannot be increased by passive elements, any reduction of the number of modes from one part of an optical system to the next will cause a red ...

Chapter 5. An Overview of Theoretical Chemistry
... In the former (endothermic) case, the energy needed by the reaction usually comes from the kinetic energy of the reacting molecules or molecules that surround them. That is, thermal energy from the environment provides the needed energy. Analogously, for exothermic reactions, the excess energy produ ...
