what is the difference between infrared radiation and thermal energy?
105798
Thermal energy is energy associated with temperature.  This corresponds to a measurement of how much the particles in a material 'wiggle'.  The more the wiggle the higher their temperature.  This wiggling causes the emmision of EM waves or light according to a blackbody curve.  Higher temps, with more wiggling, will emit more total energy and more photons at shorter wavelengths.  The hotter the object, the more infrared radiation it emits, however it will also emit more of every other wavelength too.  The peak wavelength shifts to shorter wavelengths ( higher energies) at higher temperatures.

It is thermodynamic concepts. Where the high temperature resorvior heat energy transfer to low temperature resorvior (cool), that process known as absorbtion. It can be both way either heat or cool absorbing system.

Quantum mechanics isn't the reason for thermal radiation, but the best way to describe the characteristic intensity distribution over the frequency spectrum of a thermal radiator. Read about 'Black Body Radiation'. For example:\n\nhttp://galileo.phys.virginia.edu/classes/252/black_body_radiation.html\n\nMaybe the answer to this question helps:\n\nhttp://answers.yahoo.com/question/index;_ylt=AjpE1vSPJyBC3rq3rKKZVKLsy6IX?qid=1006022704468\n\ngood luck!

infrared ray=a ray of infrared radiation; produces a thermal effect (as from an infrared lamp)\nLED=light-emitting diode: diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used

well energy is used only in the beginning to start the reaction. otherwise an exothermic reaction will give out tremendous amount of heat energy.

Actually, heat is not an actual form of energy, but instead a measure of the excited energy in an object.\n\nTrying to measure the speed of heat is similar to trying to measure the speed of decibles (rather than the speed of sound)

You have to specify the energy migration profile. Either adiabatic (zero energy transfer) or iso-volumetric (a lot of energy entering the system) or something in between.\n\nAlso, you have to specify the thermal units (Celsius/Fahrenheit/Kelvin/Rankin).

ok greenhouse effect is the trapping heat in the form of infrared raditions. let we take example of a car parked in the sun during day.\nwhen we open doors interior seems too hot. this is due to green house effect. what happens that glass allows heat or infrared rays to come in but does not allows it to escape. We all know that heat generation is due to infrared rays. So if there is too much heat anywhere there infrared rays have shorter wavelength and place having low heat have infrared rays with longerwavelength .\nSo rays with shorter wavelength enter in car but heat inside car is less compared to outer environment. Sorays with longer wavelength become unable to escape out as they have less penetrating power.

the main type of radiation produced is visible and infrared radiation but all types of radiation is produced in various amounts.

There are only two ways of energy transfer; one as result of temperature difference  and other where temperature difference is not involved. In the later we may be able to visualize it as work done by some force or we may not be able to do so. But with our pre-decided conception of energy we find that energy of one object gets reduced and the other gets increased then we say that the object/system whose energy is reduced has done work upon the object which has gained energy. The concept of energy is related to work on one hand and force on the other.

Light energy is a form of electromagnetic radiation and is found in a segment of the (EM) electromagnetic spectrum. \n\nThe EM spectrum encompasses the entire range of ionizing and non-ionizing radiation extending in frequency from approximately 1023 hertz to 0 hertz, or in corresponding wavelengths, from 10-13 centimeter to infinity. \n\nThis spectrum includes all forms of classical non-ionizing radiation we are familiar with including ultraviolet light, VISIBLE LIGHT, infrared (light) radiation, microwaves, and radio waves. The spectrum also includes ionizing radiation such as cosmic-ray photons, gamma rays, x-rays. \n\nAt eithe end of the visible light spectrum is infared and ultraviolet light and humans cannot perceive these spectrums of light.  Red colored light is longer wavelength of light and visible violet light is shorter wavelength.\n\nFor a cool chart and more in depth descriptin of the EM spectrum check out the Goddard Space Center's special page on this topic. \n\nhttp://imagine.gsfc.nasa.gov/docs/science/science.html   Use the link that says The Electromagetic Spectrum

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.

Thermal energy comes from translation, rotation, and vibration of molecules within a material.  In simpler terms, it's heat energy.

IR ray is an electromagnetic wave, like visible light, X-ray, gamma ray and UV ray(even radio waves). the energy of IR wave is lower than visible, UV, X-ray and gamma. when one of the high energy electromagnetic waves hit a molecular, they will brake it to smaller parts( if they have enough energy) but IR doesn't have enough energy, so all it can do is to make the molecules move faster. the movement average of molecules is what we call heat, so when IR hits a material, it'll rise the average molecular movement in it and we say that the material became hotter.

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.

By heat (because you use the term reflection) I presume you mean radiant heat, in which case the answer applies to ALL radiant energy.\n\nEvery photon has a particular energy determined by its wavelength. When it hits a surface this energy can be transfered to the atoms and molecules that make up the surface. However, atomsand molecules obey the rules of quantum mechanics, and so the vibrational, rotational and electron energies are all quantised. If the photon has the right energy it will probably excite the atom or molecule and its energy will be transferred to a vibration or to excite an electron. If it is not, it will be reflected.\n\nIts a bit like a guitar string. If you strike it at the right frequenecy it sounds a note, otherwise it does not vibrate.
