60. It emits infrared radiation to space. This happens constantly, not only during the night, but during the day the net energy flux is positive because the amount energy coming from the Sun is much higher. Things are complicated a little bit by the atmosphere, meaning that most of the radiation emitted from the ground does not reach …
How does an electron absorb or emit light?
From a physical particle perspective, an electron (free or bound to an atom) cannot and does not absorb a photon. The atom absorbs the photon and takes its kinetic energy. That kinetic energy causes increased vibration of the atom which can emit another photon and/or emit a loosely held/ bound electron and/or that vibration can be …

[Physics] How does an electron absorb or emit light
Another way to get atoms to emit light is to shine white light on an atom and the electrons would absorb the photon if the energy of that photon was equal to the energy difference between the energy levels. And the electron would jump to the next energy level and be absorbed. All other wavelengths do not have sufficient energy to allow an ...

What is a substance that absorbs light in plants? – Wise-Answer
What light rays do plants need? UV-A and UV-B are both good for plants. The benefits of both kinds of ultraviolet light exposure include deeper and richer plant color, increased nutrient content of fruits and vegetables, and a stronger defense against harmful fungus. UV-A is okay in any quantity, but too much UV-B can damage a plant''s DNA.
