What makes a light bulb an example of radiation?
The luminous radiation emitted by the light bulb.
Can you give some evidences that light is a particle?
Photons interact with matter as a particle; for example, photons can be absorbed and emitted by electrons.
What is happening when objects that emit light give off heat?
The most common way light is emitted is by the so called thermal emission, like for example normal lamps or the sun. In this case a certain amount of heat is emitted while emitting light. Naturally the object can also be cooled much sooner for example with a cooler (if it is not the sun naturally :-) ). Since the color (frequency) of the emitted light depends on temperature while the object cools the emitted light changes color from blue to yellow to red to infrared and so on down to microwaves. There are however other means of emitting light exist, by laser effect for example. In this case the effect of cooling is strictly related to the type of laser material and optical pump used and it seems to me out of the scope of this short answer to discuss this point.
What kind of light is emitted by growing lights?
The light that is emitted by growing lights is a light that can closely mimic that light and warmth of the sun. These lights are considered HID lights and emit a more intense light than a florescent light.
What different forms of emitted light are there?
fluorescence
What makes a light bulb an example of radiation?
The luminous radiation emitted by the light bulb.
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
Is a bright star an example of emitted light?
Every visible star is an example of emitted light, regardless of how bright it seems. Several invisible ones are too, even though there are external reasons why they're invisible to us.

What light gets emitted by tanning lamps?
Ultraviolet light
Is light emitted in waves?
Yes, but it is also, at the same time, emitted in particles (photons) too. This is called the "wave-particle duality" of light.

What is infrared light emitted by?
the surface of the atmoshere.
What is the difference between emitted light and exciting light?
excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state. emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.
