how is light energy turned into heat energy?

By capturing the light and storing it.\nFor example capturing the sunlight inside the glass chambers filled with special metal foils that will get heated and then can be used later in solar energy.\nSo, that we can use that energy to heat, light, cook, and many other things.

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

One way it actually interacts is by catalysing chemical reactions-various spectrums of light increase atomic bonding between different chemicals and atoms. Of course there is heat, the solar radiation excites atoms and increases their activity, generating heat. Most everything else is optics, like things we say as white reflect almost all the light hitting them and things we see as black absorb the entire spectrum of visible light.

In physics, heat is defined as energy in transit.Generally, heat is a form of energy associated with the motion of atoms, molecules and other particles which comprise matter. Heat can be created by chemical reactions (such as burning), nuclear reactions (such as fusion taking place inside the Sun), electromagnetic dissipation (as in electric stoves), or mechanical dissipation (such as friction). Heat can be transferred between objects by radiation, conduction and convection. Temperature, defined as the measure of an object to spontaneously give up energy, is used to indicate the level of elementary motion associated with heat. Heat can only be transferred between objects, or areas within an object, with different temperatures, and then only in the direction of the colder body.\n\n\nfor elaborate details refer to the link below:\n\nhttp://en.wikipedia.org/wiki/Heat

Heat is generated through inefficient energy reactions in our body.\n\nAs you may remember from physics class, no reaction is 100% efficient - for example: In a light bulb, not all of the electrical energy in converted into light; some is converted into heat.\n\nThe same is true of our cells, and a some of our energy is released as heat (instead of what is intended!) Muscle movement is especially inefficient, with a great deal of the energy used for muscle cell contraction given off as heat. This is why you get hot when you do exercise!!

Yeah man...light is one of the most energetic forms that we witness. Light actually has many types of energy, just like most other things. \n\n1) Photons of light (of a suitable frequency are capable of imparting enough momentum to an electron in a metal so that the electron leaves the metal's surface. This is known as the photoelectric effect and the credit for it's knowledge goes to Mr.Einstein.\n\n2) Light has heat energy, and therefore thermodynamic value. You'll see that if you stand in the sun too long, you will be hot. \n\n3) The thermodynamic energy of light causes photochemical reactions, such as the radicalisation of halogen atoms, or the redox reactions of alkyl halides. \n\nI cannot be too sure of my satisfaction quotient with this answer because your question overlays so many fundamental concepts of light. For example, you wouldn't ask a rolling ball, "Excuse me sir, but how much energy do you really have?" The ball will snicker because you have not specified WHAT KIND OF ENERGY you want from the ball. Now, if you were to ask, "Excuse me sir, what is your KINETIC energy?", the ball would happily answer that it would be half of its mass multiplied by the square of its velocity. \n\nOne of the kinds of energy does involve a mass parameter and that would be the photoelectrical energy of light. This energy functions on the sound premise that linear and angular momentum are conserved, and since light has dual (mass-wave) nature, this kind of energy does involve mass. \n\nWe know that the energy of a photon of frequency v is E=hv where h is Planck's constant. We also know that the energy of a photon in relation to its mass is E=mc^2. THus we can say:\n\nmc^2 = hv.\n\nAll right, here is a clear answer, which I just realized. \n\nOne photon of light has the above mentioned amount of energy, and therefore a ray of light will have the energy of how many ever photons are in the ray of light. \n\nSo for n photons, energy of the ray of light is nhv. \n\nNow THIS nhv can be CONVERTED into all of the forms mentioned above. Light has energy which is capable of doing different kinds of work. \n\nForgive me for the error of thinking that light has different forms of energy. It has one form of energy which can be CONVERTED into different forms of energy. Phew....\n\nI really must thank you as this was a learning process for me too.\n\nAyerhs.

When heated the electrons move from the ground state to an exicited state.  They are unstable here and return to the ground state giving off energy in the form of a specific color.  Different energy levels will produce different colors

Thermal energy is heat that comes in 3 forms: conduction, convection, and radiation.  Conduction is when you are cooking on a stove and the heat passes through the metal in the burner and into the pan.  Convection is when air passes over a warm surface and rises or moves because of the increase in energy and takes the thermal energy with it.  Radiation is how the Sun brings energy to the Earth and other planets.  Thermal energy is measured in Joules (J for short) or British Thermal Units (BTUs).  The transfer of heat is measured in Joules per second, or watts, and BTU/hour.\n\nIts use is almost every aspect of our lives, from your body keeping itself warm to cooking to keeping your house warm to chemical reactions that generate heat.  If you want to study thermal energy, you might major in Mechanical Engineering or Physics in college.  I have a degree in Mechanical Engineering.

lol tahts simple and im 12! its not energy to mass its mass to energy! and atoms dont swell they simple crush together forming heat. as they hit light speed they disinegrate... or as thosse scienticsts say...

The absorbed photon may be re-emitted as either reflected or refracted light. If it is absorbed, its energy is converted into heat. In some materials, a high-energy photon will stimulate the emission of a lower-energy photon. This is called fluorescence.

heat is a form of energy.

the fusion of light atoms to make energy at near room temperatures. There was alot of hype about this several years back when a physicist claimed to have achieved cold fusion, but his results weren't reproducible and he was discredited. \n\nPersonally I don't see how it's possible even in theory how cold fusion could work, the energy just isn't available to sustain any sort of reaction at room temperatures.

Anything the energy can be converted to use for.\n\nUsually it is light and heat though.

well I think you are asking how to turn heat into energy.  what it dose is heats a jell in a tube and this heats water out side the tube and the water turns to steam that turn a turbine that turns a motor what produces energy. the water cools falls back into the tank and it get heated up again. so it is a never ending cycle.

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.

The answer is a\n\nBecause when atom are split or fuse together there masses are always less then the sum of the reactants. the lost mass is transformed into energy. The energy is in the form of the following: Gamma rays, ( very high frequency  x-rays) Beta particles ( a electron shooting away from a atom), or Alpha particles ( a helium nucleus traveling at a very high speed) along with the resulting atoms that are split or fuse; moving at a  higher speed than before. That makes a lot of heat ( which is the definition of heat: a lot of atoms or molecules in motion.) This is in accordance to Einstein famous formula E= MC square. This is what powers our sun and the stars in space by Nuclear fusion, along with the interior of our planet and nuclear reactors and  atomic bombs by nuclear fission.

heat radiation is possible in a vacuum, thats how the suns energy reaches us
