What causes fluorescence?
Fluorescence is glowing, or giving off light.
What is mean by thermoluminescence?
According to Wikipedia: "Thermoluminescence is a form of luminescence that is exhibited by certain crystalline materials, such as some minerals, when previously absorbed energy from electromagnetic radiation or other ionizing radiation is re-emitted as light upon heating of the material." You can read more about this phenomenon, below.
How does infrared light reflect off objects?
Infrared radiation or light is part of the electromagnetic spectrum and acts the same as visible light does.Infrared can be absorbed and reflected by objects much the same way as visible light. More on Infrared:Some black objects that absorb visible light radiation may reflect infrared.Much of the absorbed visible light energy is re-emitted as infrared up to many hours later.There are subcategories of infrared, two common ones are near-infrared and far-infrared. Near being closer to visible light.
Why do the metal ions radiate energy as light?
Metal ions radiate energy as light because of the electrons. The electrons that are moving around the nucleus move in spaces called orbitals. When an electron is zapped with energy (usually electricity) the electrons absorb that energy and jump to a higher energy level than at which they were. As the electrons lose this energy, they fall back to their ground state or their "normal non-excited state" and they emit or release the same amount of energy that they absorbed or the equivalent to the amount they absorbed in the same amount of levels that they dropped down. The energy that is emitted is what we know as light, but they also emit UV and infrared radiation.
What does a wave do to create reflection?
The energy, or photon, is absorbed by the molecules on the boundary of the reflecting material from the direction of propagation of the light source. Then the energy is re-emitted in all directions by the molecules. But the next layer of molecules in the medium absorbs the light going into the material and the light exiting the material is the re-emission of the light wave; aka reflection.

Solar radiation that is not reflected by Earth's systems is absorbed This absorbed energy is then reradiates as what into space?
This absorbed energy is then re-radiated as heat
Which biome has the highest net radiation budget value?
It's actually the rain forest because that is the biome closest to the equator, meaning that it has a net radiation budget surplus (more solar radiation is absorbed than reflected/re-emitted as infrared radiation), unlike the biomes closer to the poles which will have a net radiation budget deficit (more infrared radiation is re-emitted/reflected than solar radiation that is absorbed).

How does the energy produced in the sun reach the surface?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
How does the energy created in a star change as it moves through the layers of a star?
The mass that changed to energy when fusing hydrogen-1 to helium-4 is released as photons of radiation that is absorbed and re-emitted by atoms. It takes 1 million years for the radiation in the center of the sun to reach earth.
How does energy produced in the core of the sun reach the surface how long?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.

What is the differences between phosphorescence and fluorescence?
Fluorescence is light energy produced by a process where high-energy radiation (such as ultraviolet or X-ray) is absorbed by electrons surrounding an atom and is re-emitted as light energy.Phosphoresence is light energy produced by a particular type of chemical reaction where the excess chemical energy of the reactants is given off as light energy.
Does a plane mirror show your actual structure?
No. It shows a simple 2 dimensional image formed by the optical wavelength EM energy (light) reflected (absorbed and re-emitted) by your body.
What occurs when radiant energy is reflected back into space?
Solar energy that heats the surface is re-radiated as infrared radiation, some of which is absorbed by the atmosphere in the process. Water vapor, methane, and carbon dioxide can all collect this re-radiated energy to some extent.
How does the suns core transfers heats to the surface?
In part through convection, but most regions of the Sun or non-convective; as a result, heat transfer is mainly by radiation: a photon gets absorbed by an atom, then it gets re-emitted soon.
