what links the heat has with light indeed they are different form of energy if we have heat we have 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.

Thermal energy IS heat.

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

light and heat are both electromagnetic waves. Light is in the visible spectrum, and heat is in the infrared spectrum, which is right next to the visible spectrum, but below it. \n\nThink of a coil spring. Look at it from the side. The cols are like waves. Light waves are spaced a certain distance apart. When the spring is stretched, the waves have lower energy and take up more space-- they are longer. These are heat waves and radio waves, compared to visible light.\n\nNow, suppose that the spring is squeezed together rather than stretched apart. This time, the waves are closer together, and have a higher energy. These are ultraviolet waves, or (depending on how high their energy goes) x rays, or even gamma rays.\n\nSo, all the waves are related, it is just how much energy they have that makes them spread out or crowd together. Visible light just happpens to be in the middle, the colors we can see.

This is because when heated, the atom gains energy. The electron in the atom will be excited to a higher energy level. After a while, it would lose the gained energy and release the gained energy in the form of light. Hence, coloured light is produced when they release energy. Some elements only produced certain colour because of the energy required to excite from one state to another are different from other elements. Elements can only be excited from one state to another with specific energy. In other word, the energy is quantised. This is related to the quantum theory. More info can be found on the net and textbook.

In my opionion, It is more like a very tightly compacted wave, of which light is a part. When matter is released back to it original wave state it emites, heat wave, sound wave, and a full spectrum of radiation waves from micro, to light, to gamma and everything that surrounds that visible and invisible spectrum.

Well energy is related to mass by the formula E=m*c^2 - so mass and energy are interchangeable. Photons do not have mass, but they still have energy. The energy of the photon is given by E=h*f (h is Plank's constant, f is frequency). So the higher frequency the light is, the more energy it has - gamma rays have more energy than radio waves etc. Because photons travel at the speed of light there is a problem. Special relativity tells us that anything with mass cannot go at the speed of light. But yes, usually things with energy need to have mass. Photons are simply different, they do not have mass but they still have energy which is proportional to their frequency.

Matter Is Energy\n\nOkay, here's an explanation. Energy = Mass x Speed of Light ^2.  Well, the speed of light is a very, very large number meaning that if you take even the slightest bit of matter  (M) and multiply it by the speed of light squared, you get a huge number, exactly equal to how much energy is in the matter.  This is what makes atomic bombs, and the sun, so powerful.  The sun converts matter into pure energy.  If you 'zoom in' on matter, you will see molecules, then atoms, then subatomic particles.  These particles are composed of, and bound by, pure energy.  Thus 'Matter IS Energy'.  Regards :)

As electricity flows into certain atoms (which make up LEDs), energy is transferred to the electrons in the atoms.  Those electrons absorb energy and rise to a higher excited state.  At some later point in time, those electrons fall to a lower energy state.  The difference in energy between the higher state and the lower state is emitted as a photon.  The amount of energy in the photon determines the color.

Maybe you want to think along the lines of a change in energy state and a resultant heat ( gain or loss ) absorbing light in a given wavelength range.

If you want to look at it on the atomic level,\nyou can think of light as a photon (a packet of energy).\nThe photons can be absorbed by the electrons around the atom which will excite them into a higher energy state.  When the electron falls back down to the ground state, it gives off a photon with a specific amount of energy.\n\nhttp://www.amazingrust.com/New/beta/Experiments/background_knowledge/Spectroscopy.html

Some are photo electric...they turn light energy into electricity.\n\nSome are heat collectors...they store the heat and transfer it to the hot water heater.

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

Energy can go from place A to place B (think about sound and light)\nEnergy can go from object A to object B (think about a collision)\n\nTh

light is (in a nutshell) waves of energy. Waves (in general) travel in a straight line. stars are so far away that not much of their energy or waves hit the planet.

Ther are two natures assigned to light\n1.It is made of particles called photons\n2.It is an electromagnetic wave.
