Infrared light doesn't "give off" energy; in this case, it IS the energy.
This is true of LED lights
THe light bulb emits light while in the process heat in the infrared spectrum is emitted.
Yes.
Infrared Radiation is at a Frequency that is outside of the range of the Visible Spectrum. Visible light does not 'become' Infrared Light. If a light source is giving off energy in the form of HEAT it is emitting Infrared Energy, as well as Visible Light. A light source can also "Heat" matter by giving off energy such as X-Rays, or Gamma Rays, or more commonly MICROWAVE Radiation.
Heat energy. When it is radiated off from the filament, it is mainly infrared light.
Many light frequencies give off heat. Infrared is one of those frequencies.
When electrons fall to a lower energy level, they give off energy in the form of light.
Yes the sun does give off solar energy. It also gives off heat and light energy.
Electrical energy can be converted to light. In addition, nuclear energy as in a nuclear weapon will give off a blinding flash of light. Also, using fireflies as an example, chemical reactions can also give off light energy.
There is actually no certain 'part' of the atom that gives off light. As you know, light is made out of photons. Photons are given off by the atom when it releases energy to get rid of the energy. I hope this helps!
Yes
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.
