what is the production and transmission of radiant energy called?
470787
Radiance and spectral radiance are radiometric measures that describe the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle in a specified direction. They are used to characterize both emission from diffuse sources and reflection from diffuse surfaces. The SI unit of radiance is watts per steradian per square metre (W·sr-1·m-2).

for radiation - how about someone sitting under the sun? Radiant energy is what heats you from the sun.\n\nFor convection (you seem to change your mind if you want convection or conduction info) you could think in terms of how a convector heater works - the warm air circulating the heat around the room. Convection also applies to liquids too - think of the water in the kettle and the water currents inside making all of the water heat more-or less together.\n\nFor conduction, how about a saucepan sitting on top of a cookers' hotplate?\n\nHeating by radiation is through infrared heat - from the sun, from a light bulb - even a bonfire but that can also be from convection too. Think in terms of "heatwaves" with radiation perhaps.\n\nConduction of heat is when two surfaces of dissimilar temperature are brough together. Some of the heat will travel by conduction (touching) to the cooler object.

None.\n\nCalories are a measure of the heat content of objects.  If you are referring to the amount of heat radiated by the earth, it would be stated in some unit appropriate to the measure of radiant energy, such as watts or newtons per second.\n\nYou may be able to find an answer by visiting the library or using the internet.

Heat energy from the sun travels through radiation, as opposed to convection and conduction.

'Spectral' indicating some kind of control based on light emission?  Where will the light energy come from? (It's dark inside people).\n\nThere are already delivery systems based on dissolution, is that what you mean?

Okay.  Well, usually it's like this:\n\n1. The first energy transfer depends on the kind of power plant, but the principle is a Fuel->Heat/Kinetic energy transfer.  In a nuclear power plant, the first transfer is Nuclear->Heat, in a coal plant, Chemical->Heat, etc.\n\n2. This heat from the initial reaction is used to boil water.  The energy remains in the form of Heat/Kinetic energy, but is simply transferred to the water.\n\n3. The steam turns a turbine.  Still kinetic energy.\n\n4. The turbine creates an electric potential.  Kinetic->Electric transfer.\n\nTo sum up: fuel reacts, boils water, steam turns turbine, turbine makes electricity.  Chemical/Nuclear/what-have-you -> Heat/Kinetic(in the water) -> Kinetic(the turning turbine) -> Electric

I think what you are really asking is what different forms of energy convert to other forms of energy.  Mechanical energy can be converted to heat through friction.  Electrical energy can be converted to sound energy with the use of varying electrical currents and permanent magnets.  The splitting of atoms releases huge amounts of electromagnetic radiation of a huge variety, from electrons, to photons, heat, light, etc.  Light energy (photons) can interact with semiconductors in solar cells to produce electrical energy, also known as electromotive force.  I am sure someone has a comprehensive list of the primary energies that we know about.  \n\nIt may help, however, to discuss energy in terms of storing it.  Gas under high pressure in a closed cylinder has high potential energy.  The release of this pressure can cause thrust (like a rocket), or cause a super-sonic shock wave that can blow things up.  Certain chemicals have energy stored in them which is released through chemical reactions.  A rotating wheel has energy stored in the mass about the rotating axis, known as rotational momentum.  The magnetic field in an inductor, like a vehicle ignition coil stores energy in the field in the core, and releases it when the current to the coil is interrupted.  \n\nIn simpler terms, mechanical energy can be turned into heat, light, electromotive force, or pressure. Chemical energy can make heat, light, electromotive force, or pressure (not a complete list).  Atomic reactions (fission or fusion) release huge amounts of energy all across the electromagnetic spectrum.  Hope this is food for thought...\n\nSee a study of thermodynamics and entropy.  It would appear that all energy flow is headed in only one direction, always at a net loss.  See the link.

Both are true, this is because heat IS light.\n\nHeat is actually the common word for 'Infra Red Radiation'... but of couse heat is shorter and easier to say. IR radiation is a form of 'light' that is just beyond our visible spectrum.\n\nWhen any type of light hits matter it causes the molecules to vibrate, this can cause IR radiation to be released, thus being felt by us as 'heat'.\n\nLikewise, when molecules are heated up, such as in a fire, they vibrate and can often release light that we can see.\n\nA fire, for example, releases a large amount of light in the red area of the spectrum thus appearing red and yellow... this happens to be near the infra red part of the spectrum, so it is hot too.\n\nCOMPLEX VERSION:\nIn an atom there are electrons, when light hits an electron it gains energy. The electron then slowly looses energy in the form of electromagnetic radiation.\nElectromagnetic radiation that is releasesd is dependant on the element, bonding involved, and the electron orbital. thus a wide variety of light can be given off.\nLight can include both visible light and infrared light... infra-red light being that which causes us to feel heat (due to its ability to vibrate the molecules of our bodies).

Heat energy.\n\nThere is water (or a water mixture) cooling the core directly.  This water is radioactive.  You then have coils running in the water which have other water (protected from the radiation) coursing through them.  This water gets the heat transfered to it and turns to steam.  The steam runs turbines that turn a magnet core in the center of a copper coil that in turn produces electricity.\n\nHope this answers it for ya, feel free to email me!

If the radiation increases the energy level of the molecule (like boiling water in a microwave oven) heat is transferred.

The electromagnetic spectrum is just a classification of the various types of light. So you are asking whether the sun uses light? Well, it certainly *emits* a lot of light and there is a lot of electromagnetic radiation (i.e. light) inside the sun, but past that, it's not clear what you want.

Basically energy derived from steam or heat escaping from deep underground.  Kinda like harnessing "Old Faithful".\nHTH

I am going to take a guess and say the moon.\n\nNo, I am kidding, it's the Sun\n\nSolar energy can be converted in to electricity and heat.

Of course energy is transferred  in energy transformation . How heat can be transferred in mechanical energy transformation or chemical energy transformation . There are  different type of energy like mechanical energy , heat energy, chemical energy and nuclear energy .  The Energy transform in  form of  qunta. Minimum energy transferred will be   h f ( frequency) . h is Planck's constant .

The same way all lasers work.Light energy is bounced back and forth within the structure of a certain material (rubies work) until the atoms are "pumped" into an excited state.  When the atoms of the material are excited enough, they emit light of only one wavelength (coherent light).\nCoreherent light will travel out whatever size aperature the device has, and not be inclined to spread and dissipate the way full spectrum light does.

Every atomic fission releases excess energy in a variety of forms.  That excess energy is trapped by the reactor in the form of heat, which is used to generate steam to drive turbines which generate electricity.

The Sun produces energy through a process called "nuclear fusion." This is the same process that happens in a hydrogen bomb. The Sun converts hydrogen into helium, and that conversion process releases energy, mostly in the form of heat. The Sun "burns" about 600-million tons of hydrogen every second.
